Find the Value of k in Quadratics for Different Scenarios Involving Roots | Step-by-Step Explanation

[Exusiai]

Man I understand this better than my teacher's lecture

[coconutrosal]

You helped me answer a question that I've been solving for days THANK YOU SO MUCH!!

[patrickmashiane]

2 days before my exam, just wrapping up my weakness and this helped out

[cleyahladra]

Hi sir, thank you for making this video, you help me a lot

[oladipodaniel]

a. k=20 or k=-20
b. k<-20 0r k>20
c. -20<k<20 / k<20 or k>-20
d. k≤-20 or k≥20
Thanks very much for the explanation🙏🏽. I can't believe it was really this simple😮, too bad I already skipped the question in my exam😅

[mohammadabudarda]

Thank you so much sir ! This video really helped me and now I am able to solve questions on rs aggarwal thank you ❤️😀

[Ricky]

Great, understood,
Plzz give me link of video in which we can identify by seeing that what are the type of roots in quadratic eqn . Iam preparing for iit jee

[disalure]

I have my test in 30 minutes and this helped a lot😭🙏

[sblnseq]

I can't believe it can be this good

[thegamer]

Thank you so much ... Finally I understand it 💕

[AimzIIT]

Yeah That graph made me exactly understand what i wanna😇

So there are 5 possible Discriminant Natures
1.) 2 distinct rational roots D>0 (and a perfect square)
2.) 2 distinct irrational roots D>0 (but not a perfect square)
3.) Equal roots D=0
4.) Imaginary roots D<0
5.) Two real roots D>=0

Wonderful explanation sir. Thank you sir

[ashwini]

Q:5x^2+Kx+20=0
Soln: a =5, b=k, c=20
∆=b^2-4ac
a.equal roots ( -200, +200)
b.two distinct roots(k<-200 or k>200)
c .no real roots(-200<k<200)
d.two real roots(k<=-200 or k>=200)
Sir, I finished what would you gave but now I typed only the final answer

Please help : Find the set of values of k for which the equation kx^2 - 3kx + 16 = 0 has no real solution

[roycebwalya]

Show that the equation (k+1)x^2 - 2x - K has a solution for all values of k.

[yrqyepc]

Hi sir, what if the equation is x^2 - 2kx + 25, when it has two distinct roots? I tried solving it the same way and it resulted as k>7 or k<-7

[kidusfikre]

Thank you very much sir, this helped out a lot

[sayedhassensayedifraan]

I have a question sayin the equation has distinct real roots what am i supposed to do ? 😢
