ok sir A rational equation is an equation containing at least one rational expression. Rational expressions typically contain a variable in the denominator. For this reason, we will take care to ensure that the denominator is not 0 by making note of restrictions and checking our solutions.
Yes t w i c e. Tama ang description mo. 👍😊 Very good.

Sir I just wanted to know what will we do if the given is a decimal number? will we convert it to fractions or just let it be a decimal?
Hello Celline, thanks for your inquiry. That depends kung saan kayo mas nadadalian. If you are comfortable to answer the word problems with decimal numbers given, that will be fine.
If you want to convert it into fraction, that will also be okay. 👍
You will still came up with the same answers. 😁
@@sirchad Thank you so much for your great help I really appreciate it..... I'll make sure to tell my classmates about youu 😁😊

Sir how can I get the right given numbers for representing?
Hello Ma. Teresa. You will just based the representation in the given situation in the word problem. You need to understand first the worl problem sentence by sentence. 👍😊
Thank you po sir❣️
You're welcome Zayin. 😊
hi sir pa notice just ask this problem sir?a ball is shot from a cannon into the air with an upward velocity of 40ft/sec.the equation gives the height (h) of the ball at any time (t) is:h(t)= -16t squared+40t+1.5
find the maximum height attained by the ball.
Hello Maryjoy. Thanks for your question. 😊 If you can, we can discuss this directly. On my Facebook Page.
I'll wait for your message. 😊
Sir kailangan po ba nung area na magkaroon palagi ng squared?
Hello Gerwin. Ang formula ng area is Length times Width. If both dimensions are unknown, therefore, your equation will always have square. 😊
Salamat po kuya 😊
Welcome Jeah. 😊
Sir Nalilito lang po ng kaunti... Bakit po sa ibang given nilipat po yung mga nasa right side ng equation all the way to the left side ng equation? Tapos yung sa ibang given naman po yung mga nasa left side ng equation ang inilipat sa right side?? Tanong lang po. Salamat po.
Hello Jaimie, salamat sa iyong tanong. 😊 We are transferring terms all the way to the left side of the equal sign for it to be at standard for of quadratic equation. 👍
Nililipat naman natin ang ibang terms sa right side kapag naghahanap tayo ng value ng "x".😊
Hope that my answer helps you. 👍😊
If you are still confused, you can always message me in my Facebook Page. 👍😊
Yiii tenkyu po sir. After 1 week natapos ko den yung math ko WAHAHAHAHAHHAAH
You're welcome Coffee. 😊 It a good news na natapos mo na sya. Keep it up! 😉👍
Good Afternoon Sir. sir pano po pag speed of car and truck,time related to how long 2 teacher check o kaya number exceeds and reciprocal o kaya solving ralated to the room and money????????

@@sirchad 1.) Filomena Resort rented a certain number of function rooms for php 28, 800 when the price was reduced by php 20 per room, 6 more rooms were rented. How many function room were rented?
Yan po sir😊
3.) Mrs. Cesa can finish checking 40 item test ahead of Mrs. Saburao by 1 min. Together they can finish 27 papers in 1 hour. How long does it take each to finish checking one paper?
sir how about this question....
The length of the floor is 8 m longer than its width and there is 20 square meters.
Hello Puts, thanks for your question. ☺️ Can you please complete the question? "there _______ is 20 square meters"
Is it the area? 😁
sir yun lang po nakalagay e
Sir pls what is the best to understand and remember this lesson
Hello Carl, salamat sa tanong mo. 😊 The most important thing that you must understand in answering word problems is to always think what is ask in the problem. Next, look for the clues or given to find what is asked. There you have it. You can solve it afterwards. 😊
Pano po yun Sir Chad kapag i ta-transfer naman po yung given into word problems.? HAHAHA tanong ko lang po..😁😁😅
Hello Honny, good day. What do you mean transferring the equation into word problem? Can you please send me the problem you encountered this?
You can send it in my Facebook Page if you want. 😊
Hi sir chad tanong ko lang po paano po pag may decimals na like the length of 0.9m more thatn its width and its area is 0.36m ganun parin po ba? Sana po masagot nyo 😊
Hello -In Zay-, salamat sa iyong tanong. Based sa given word problem, kapag kinonvert mo sya into mathematical expression, it will be:
L = W + 0.9
A = 0.36
Same process pa din ang gagawin kahit na decimal values ang binibigay. 👍😊
Thank you Sir Chad naiintindihan ko na po 😊
@@nico_zy you're welcome -In Zay-. 👍
sir ask lang po...pano po ba magcompose ng word problem? and yung given po..pano po ba makukuha ung mga measurements?
pano po ba magcompose ng given?
@@g07-escobarnicoleannec.38 hello Nicole Anne. Thanks for your question. 😁 You just need to dig deeper and understand the given word problem. From it, you can understand what are the given and what is asked for. 😁
Sir ask ko lng po pano po nakuha Yung 7.899s at 0.1013s?
Thanks po sir,have a good day🤗🤗🤗
Hello Venice. Thank you sa tanong mo. 😊 You can use your calculator to simplify or convert to decimal number the square root. 👍 After that, you can continue the same process on how you simplify the quadratic formula. 😉
@@sirchad thanks sir Chad for replying my question now I know hehe.keep safe po
@@veniceflores3450 you're welcome Venice. 😊
Hi sir curious lang po. How did you get the seconds in the last problem?
Hello Jaycee, salamat sa iyong tanong. 😊 Nakuha ko ang seconds in the last problem by solving the given relation or quadratic equation using the quadratic formula. And sa pagsisimplify ng mga square root na walang exact na answer, you can use the calculators on your phones to find the decimal value of the square root. 😉
Sir how did you get the decimal of speed sa example 2? Ano po yung step na ginawa nyo po sa calcu? :(
Hello Mary Angel. Thanks for your inquiry. 😊 Pwede mong makuha ang decimal ng speed through finding the square root of 95, then multiply it by 4, that will be the answer for 4√95.
After that, you can proceed with the simplification of the quadratic formula. 😊👍
Thank you po sirrrr💛
@@ary0270 you're welcome Mary Angel. 😊
Hello po sir😊😊tanong ko lang po. Paano po kapag yung problem is decimal ang given?
Hello Jamaica. Salamat sa iyong tanong. 😊 Same process lang din ang susundin mo kahit na decimal number pa ang given sa word problem. 😉👍

Sir paano po pag speed hinahanap?? Plss po pasagot
Hi Lexy, thanks for your inquiry. Can you send a problem you encountered speed? If you want, you can directly message me in my Facebook Page to discuss it. 😊
Salamt po
You're welcome Jonalyn. 😊
Sir pano po isimplify yung last example po? yung cinalculator nyo po hihi sorry for disturbing, thankyou po!!
Hello Jom. Thanks for your inquiry. 😊 Pwede mong makuha ang decimal ng speed through finding the square root of 95, then multiply it by 4, that will be the answer for 4√95.
After that, you can proceed with the simplification of the quadratic formula. 😊👍
sir paano po pag speed ang hihanap
Hello Ckrizel. Can you please give a problem related to speed? 😊
Thanks po sir,tinry ko mag solve kaso nahihirapan po ako sa pag identify ng given.
Hope that this video helps you. 😊 Kayang kaya mo iyan, tiwala lang. 😉
Hello Dwayne, medyo mahirap lang talagang magidentify ng given sa simula. But the first thing you must do is to understand the problem. If you can, gawin mo syang taglish. 😉 Una mong tanungin sa sarili mo, ano ba ang hinahanap? Next, ano ba ang kailangan ko para makita yung hinahanap. Sunod namin, tingnan mo sa problem kung ano ang mga clues na binibigay nya.
Sa ganitong paraan at ganitong mindset, kapag nasanay ka na, madali mo nang makikita or madidistinguish kung ano ba ang mga given sa problem. 😉
Thank you so much po sir gagawin ko po iyan,tiwala lang maraming salamat po ulit.Galing niyo pong teacher😊💖nagkaroon po ako ng pag asang magsagot haha😁
@@sirchad uhm sir question lang po ulit dun po sa example no.1 nilipat nyo po sa left side yung sum ng L and W tapos yung ibang example is nilipat nyo naman po yung area sa right side,kung magsosolve po ako pano ko po maiidentify kung sa right or left po ilalagay?
@@dwaynep2726 salamat Dwayne sa iyong tanong. Nakakatuwa at mapapansing gustung gusto mo talagang matuto. Keep it up! Malayo mararating mo. 😊 Back to your question, kung saan ba ilalagay ang mga terms, sa kaliwa ba o sa kanan, ang sagot is either right or left. Pwede kahit saan. Bakit? Dahil ang aim lang natin is maequate natin sa zero ang buong equation at mapapunta natin sa kanyang standard form. So kahit sa kaliwa or kanan mo papuntahin ang lahat ng terms, basta maequate mo sya sa zero, tama ang magiging sagot mo. 😊 Sana nakatulong ang sagot ko sayo. 😊
Inabot pa ako ng tatlong araw para magets HAHAHAHAHA
Hello Precious. That's okay. Lahat tayo ay nagsstart sa small steps. Kaya mo yan! 😊👍
paano po pag. hinahanap ang speed
alam kona po
Hello Ckrizel. Kayang kaya mo yan. 😊 Keep it up. kung may katanungan ka. Don't hesitate to ask. 😉

Sir pano pag ganito A picture frame has its length 8 em longer than its width. It has an inner
1-cm boundary such that a maximum 660 cm pieture may fit into it. Find
the dimensions of this frame.
Hello Twitter. Thanks for the question. 😊 Regarding this problem, you can message me in my Facebook Page so that we can discuss this. 👍😊
hi pa help naman po itransform ito into quadratic equation.
The lenght of plywood is 0.9m more than it's width and its area is 0.35 m2
Thanks po!!
Hello love is a maze. Based on your given word problem,
Length = width + 0.9
Area = 0.35 m2
Therefore, if width will be "x", then
Length = x + 0.9
Take note that the formula for the area is equal to length times width. 😊
Area = L times W
0.35 = (x + 0.9)(x)
Once you have that equation, you can proceed and have quadratic equation. 👍😊
thank you po!!!
