Best Math lecture ever seen on RUclips!😍

[@conceptsofiitmaths7417]

Thank you 😊

[@ApteacherNetTelanganaTeachers]

I am a math teacher.... I just learn it

[@preetham_nampally7058]

Nice Explanation sir
The answer at the end is (-√3/2 , √3/2)

[@conceptsofiitmaths7417]

Yes. Thanks for the correction

[@aishwaryasinha1943]

Finally understood the concept. Thank you Sir. Great session

[@conceptsofiitmaths7417]

You are welcome 😊

Sir in example -x^2+4x-4 when we substitute x value as 1 we don't get f(x) less than zero. So that the quadratic equation should be -x^2-4x-4

[@anniesina1235]

16:35 sir how did you put 4 lambda^2 - 3 in (a^2 - b^2) = (a - b)(a+b)?

[@conceptsofiitmaths7417]

That was a mistake. Thanks for the correction. Its (2lamba+√3)(2lambda-√3)

What does delta means here

[@conceptsofiitmaths7417]

Discriminant= b^2-4ac

[@chiranjeevigonu1567]
