Greetings to the tutor and to all associated with this site.Let me say that i'm soooo pleased with your method of tutoring,everything is made sooo easy to understand.Thank you very much and KEEP UP THE GREAT WORK..
For mixed math this whole semester I've been so confused about these concepts. Finally I understand finding the discriminant! Thank you, Mr. Whitt! I am confident that I'll pass my exam tomorrow!
+Bryce Whitney That is cool Bryce! We finally get an actual response from you after we gave you your birthday gift on your birthday! We spent an extremely long time brainstorming what would be the best present 2 get 4 you. We spent a huge amount of time and resources. Resources that could have been spent on someone else. Resources that could have benefited so many other people. Time that we could have been spending with our families and loved ones. Time that could have been spent solving world issues. Time improving ourselves and doing something worthwhile. And after how long did it take you 2 get back 2 us about it? Exactly! Thanks 4 finally saying something about it! Gosh! LOL
Yes, if the discriminate is a negative perfect square the roots would be complex and conjugates which are two complex imaginary numbers. As far as descriptors are concerned, that is all most textbooks and instructors would want to know. Beyond that, you may need to ask your teacher.
@@FortBendTutoring For a second I thought it was "2x^2 - 5x - 3" ... You are right! I just got confused with as the "b" value shifts the parabola to the RIGHT of the "y" axis, then it is negative, but if it shifts to the left of the "y" axis, then it is positive.
+Mustapha Dukuly The "graph" needed to grasp the concept is the graph of the quadratic equation you're using when finding the discriminant. You're basically looking for the graph to touch the x-axis. The number of times the graph touches the x-axis coincides with the number and type of solutions the discriminant yields.
Sir square of ( differential coefficient of ax^2+bx +c )is equal to its discriminant i.e. b^2--4ac .This gives the roots of the equation ax^2+bx+c =0. DrRahul Rohtak Haryana India
@@FortBendTutoring Sir This method is given in yajurveda but no body has noticed this .I believe that this method is mathematically correct to find the roots of the quadratic equation ax^2+bx+c= 0.This correctly gives discriminant D =b^2--4ac . DrRahul Rohtak Haryana India
Ok that means you’ll use the discriminant and have it set greater than or equal to zero. Then solve the inequality for k which should give you the range of values k can be.
@@FortBendTutoring I wasn't expecting a response after 7 years lol. I rewatched and it turns out I was overthinking it and it's really simple. Thank you!
I was just confused with all these concepts and when i started the video ,, after hearing the intro tune I thought this is just waste of time and i was totally wroonggg🙏🙏
Love this video, but I'm not too sure if I'm doing it right. Example: Negative 8 x squared, plus 4 x, minus 8 equals 0. a=-8 b=4 c=-8 So I do the formula, b squared minus 4ac 16-4(-8)(-8) I end up with 16-256 And I get -240!!! Its is a really large number and it seems pretty exotic and i think its wrong. But if you were to confirm I'm doing the right process, it would be great.
According to your given values, your process and answer is correct. However, we would like to see the original problem before verifying this. Also, sometimes the answer is exotic! Lol
The original problem was negative 8 x squared plus 4 x equaled to 8. Then I subtracted the 8 over and solved from there. and lol thanks for the help. I failed to finish a math summer packet so now I'm trying to do everything before it is due.
I have no way to edit this so I just used the reply button. Anyway we had a lesson in this and our teacher reached the answer of 2i ( square root of -2/ imaginary numbers) that left me puzzling on why didn't you use the extended one/finding the numbers though the original problem?
You don't need to find the square root 2 find the discriminant. If you're solving the equation you do. Check this video out: ua-cam.com/video/iII7E1m6f9M/v-deo.html
+Fort Bend Tutoring I already know the method 1,2,and 3 😂 But the teacher answer reached 4(square root sign)-2.And I just noticed she used the answer for checking if it was correct. Thx for trying to help btw. Still don't know my teachers formula for using the discriminant to answer without factoring....
I guess I'm not fully grasping what your question is without seeing the original problem. Bottom line, the methods shown in this video will always yield a correct answer. As far as simplifying results that end in imaginary numbers, I'll leave you this link to refer to if necessary: ua-cam.com/video/uK99ImJV-Pw/v-deo.html

This guy has good rhythm. i just understood discriminant for the first time ever while it was being explained to me.
Glad it helped! Thanks for the testimony!
Whenever I'm unsure of something on my math homework. I just search for one of your videos. Works everytime, thanks!

Thank u☺☺☺☺☺
another question if the discriminant isnot positive but it a perfect square how would be the roots ?
As it states in the video, two complex imaginary numbers.
Fort Bend Tutoring thanks a lot for your feed back but i mean when the two roots are complex and conjugate ?
Yes, if the discriminate is a negative perfect square the roots would be complex and conjugates which are two complex imaginary numbers. As far as descriptors are concerned, that is all most textbooks and instructors would want to know. Beyond that, you may need to ask your teacher.
3:35 It is supposed to be "+5"
I disagree Aakash. The b value is -5 as it is the coefficient of the 2nd term in the quadratic equation.
@@FortBendTutoring For a second I thought it was "2x^2 - 5x - 3" ... You are right! I just got confused with as the "b" value shifts the parabola to the RIGHT of the "y" axis, then it is negative, but if it shifts to the left of the "y" axis, then it is positive.

Wow it really helps me thx!!!!!! Now I understand how to use discrimination yey
is determinants and descriminants the same thing? i have to learn how to do it for a college placement test
+Marnika Walker Hello Marnika! They are two totally different things. Determinants are used with matrices.
do you happen to have a video about determinanants?
you helped me so much with my algebra 1 final thankyou
You're very welcome! Happy 2 help!
Thanks .. I got 90% in Quiz .. Super Thanks :)
Great job and you're welcome!
I finally understand the concept. But, can you graph the discriminant so that I can easily grape the logic?
+Mustapha Dukuly The "graph" needed to grasp the concept is the graph of the quadratic equation you're using when finding the discriminant. You're basically looking for the graph to touch the x-axis. The number of times the graph touches the x-axis coincides with the number and type of solutions the discriminant yields.
YES!! NOW I FUCKN GET IT thanks man sooo much
Happy 2 help Daquoin! Thanks 4 watching!
I'm with you there buddy, the tutor is a g
Thanks Shandon! I appreciate the support!
what would a, b and c be, if i were given:
x(squared) plus 3
and
x subtract x(squared)
Combine any like terms you may have and arrange your terms in descending order. Then follow the steps in this video.
why do i say two real .rational ? since it is rational then it is real why do i mention the both ?
It depends on the question. Some ask you to specify whether the real answer(s) are rational or irrational. As both are real numbers.

Thank you so much mhmmmm and ahha mhhhmm.
You sure made it simplier.....
Great Nitocha! Happy 2 help!
How can I solve kx^2+4x+3+k=0
Depends on the question: Are they asking you to solve for k, x or both? Also, is this all the information they’ve given to you?
The question is find the range of value can K take in.....the same equation....👆 to have real roots.
Ok that means you’ll use the discriminant and have it set greater than or equal to zero. Then solve the inequality for k which should give you the range of values k can be.
Thank u so much....😄
I just hope I will get it correct😞
Keep at it and you’ll get it! Good luck!
I don't get it
Sorry 2 hear that! Check out another channel’s explanation on the topic.

Love this video, but I'm not too sure if I'm doing it right. Example: Negative 8 x squared, plus 4 x, minus 8 equals 0.
a=-8 b=4 c=-8

16-4(-8)(-8)
I end up with 16-256
And I get -240!!! Its is a really large number and it seems pretty exotic and i think its wrong. But if you were to confirm I'm doing the right process, it would be great.
