I'm just here trying to figure out how to get from the ice table set up to rearranging the equation for the quadratic. I am lost at how you got 6.00-5.00x+x^2 in the denominator. Do you have a video explaining step by step to get to the quadratic equation?? I get everything else besides that >.
You have to foil, or multiply the first things, then outside things, then inside things, then the last things. So if you had (1.00-x)(2.50+x) 1. First, so 1.00 x 2.50 = 2.50. You multiple the first things. 2. Outside, so 1.00 times x = 1.00x you multiple the things to the outside 3. Inside, so -x times 2.50 = -2.50x you multiple the things inside 4. Last, so -x times +x = -x^2 you multiple the last terms together The equation would then look like… -x^2+1.00x-2.50x+2.50 which adding like terms would give -x^2-1.50x+2.50
There may be something gone awry when doing the math using the quadratic equation. I always suggest doing everything within the square root first, and then once you have that value, perform your two root calculations: -b - ANS/2a and -b + ANS/2a
Perfectly done! except it was done toooooo FAAAASSSSTTTT!!!! but overall its like glue now! but you almost lost me at the 21X^2 whenmoving quad over to make one side = to 0
Maybe your teacher's strengths lie in organic chem where there is less math, or possibly in another science. Either way, I'm happy that I was able to help :)
@@josie.a.p That makes absolutely no sense on her part - if she has the skills to explain, why withhold them? Sorry that you're going through this. Just use my lessons to help you and your classmates get through.
I took a damn while trying to understand this, but that's only because I don't have any background knowledge about how to calculate what, when to calculate what, and what to calculate lol BUT this vid is a great help, now I can solve for my homeworkkk tysm for making this videoooo (╥﹏╥)
my calculator doesn't like it when I input a negative value for b in the square root. I get MATH ERROR. but from what questions I've done just always keeping it as a positive regardless gets the answer still
coco soldier I appreciate your feedback. These videos are meant as a supplement to in-class teaching for my students rather than a stand-alone course. Best of luck with your chemistry.
@@MoleqlarDon't worry about the haters. I think you did a superb job. I'm not even taking chemistry, I'm only learning it (completely out of context) to help my girlfriend with her homework and I still managed to understand just about everything in this video completely. Nice work!
Who's here watching to prepare for the test tomorrow?
Got a nice 40% final tmr and i still dont know ice tables xD
nah i'm here for the test in two days
So, did you pass your test?
@@Moleqlar yeah but I flunked my cross curricular :(
Wow, explained perfectly! Thank you so much! ❤️
Awesome job at explaining the steps. Thanks a ton!
Esmir M. Thanks! Glad it helped!
thank you so much, all is clear now. still a useful video after 7 years!
Thank You For your expert explanation and great narration have a great day !
I love your quadratic method ❤️👍🏾Thank you for teaching me something I didn’t know

@@slopcrusher3482 i Love you thank you so much for explaining thattt i was so confused
Thanks so much ...I hope this comes in the exam
the challenge i had has been sorted,ICE method of finding missing concentrations,thank you so much. moleqlar
My pleasure! Good luck.
dont wanna sound dumb but how did you got (6.00 - 5.00 + x^2) at 7:22 ?
By "foiling" (2-x)(3-x).
2*3 = 6.
2*-x [in second bracket] = -2x
3*-x [in first bracket] = -3x
-2x + (-3x) = -5x
-x * -x = x^2 [no operator means +]
The put it together.
6 -5x +x^2
Moleqlar okay thanks so much
@@Aaa-cf4dx im with you, where did the 5 come from? i get that 2x3 is 6, then -X x 3 is -3x...not 5
@@Jess-gr8kv 2*-x and -x*3 = -2x - 3x = -5x (original writer omitted the x)
How did he get 5.00x?
you made it look so easy. thank you so much
thank you so much honestly i understand it so well now 😭🙏
I love this video! Thank you so much.
great video.
Love your work mate
Thanks Heath. Still so much to cover so I'll be coming our for more videos shortly
Thank you so much❤😍😍💕
My pleasure 🙂
thanks! such a great explanation (:
What do you do when both results from the quadratic equation are negative?
There may be something gone awry when doing the math using the quadratic equation. I always suggest doing everything within the square root first, and then once you have that value, perform your two root calculations: -b - ANS/2a and -b + ANS/2a
Thank you!! Helped tremendously
You're amazing
Thank you for this!!

My chem teacher told us to use this but never taught us how because "she's not a math teacher"

@@Moleqlar shes also a math teacher but I think she was saying it because she's not OUR math teacher at the moment. Ahh so annoying lol

Thank you!!!!
My pleasure. Hope it helped!
There is a mistake when you move 4x^2 to other side.It would be negative so they can add and become -29x^2
25x^2 is positive and switching 4x^2 to the other side would become negative therefore you have to subtract
thank you so much
I got a problem in chosing value of x because both value smaller than initial concentration
life saver !!!!

It's all about the order of operation. Try using brackets or if your calculator has a specific quadratic function, try using that.
@@Moleqlar No worries, hope I don't need any chemistry units in future
Since these are gasses, why didnt you use Partial Pressure instead of Molarity?
Kyle Bartek you would get the same answers
It asked for Concentration of each gas. Not the partial pressure of each gas.
Thank u so much. Love from Pakistan
My pleasure! All the best with your studies
Holy fuck your amazing. Thank you sooooo much
thanks my dude
You're welcome, dude.
Moleqlar you been a little bored recently I presume?
@@1Dann123 Hahaha quite the contrary! But I noticed that there were some comments I never responded to (apologies) so I just did my best to respond 🙂
Moleqlar 🤙🏻🤙🏻🤙🏻🤙🏻🤙🏻
Is there a simplification for quadratic equation
Unfortunately no, this is as simple as it gets 😕
Thank uuu
Thank you for watching and for your comment 🙂
I keep getting answers with imaginary numbers trying this in my calculator :(
-125-55=-180 no?
Dismal job at explaining.... you're meant to be attempting to teach i assume? not racing through an exam question

they make sense even out of context. you might need some more math help vs chemestry stuff, i recomemd you visit krista king for in depth math help
