The roots will be equal if b = 0
Let the roots be y and (-y)
We know, b = sum of roots.
So, b = - y + y = 0.
➡️ Option (a) is the answer.
THANK YOU

explain how?
I think Ans will be zero. since sum of Roots is zero here. and sume of roots = -b/a = 0. so b=o
it's a formulae..
No It won't be zero
okay,I got it
if one root is 'x' then other roots be '-x'. sum wilk be x-x=0. and Sum of roots is equal to -b/a.
Ans will be A. 0
oh yes,Its true..thank you
