Let ax2 + bx + c = 0 If the sum of the equal roots is equal to the product of the same
roots.Then which
of the following hold true
(a) a + b = 0
(b) a = 0
(c) c = 0
d) a + c = 0

• 1 option is missing in that one option should be b+c=0 ans

• Given ax2 + bx + c = 0,We know sum of roots= -b/a and product of roots=c/a
  Therefore according to the given question -b/a=c/a
  and given sum of equal roots ,Let w be equal root then 2w=-b/a & w2=c/a
  on solving we get discriminant(b2-4ac=0) and a=0 is the answer
