Question

Ax2+bx+c=0 has equal roots then c is equal to

Answer 1

The Given Equation is

ax^2+bx+c=0

If the roots are equal then the discriminant is 0.

b^2−4ac=0

⟹b^2/4a=c

Hence the required relation is

c=b^2/4a

Answer 2

SOLUTION :  

Option (d) is correct :  b²/4a

Given : ax² + bx + c = 0

This given equation is the standard form of quadratic equation. Therefore, D(discriminant) = b² – 4ac

D = 0 (equal roots given)

b² – 4ac = 0

b² = 4ac  

c = b²/4a  

Hence, the value of c is b²/4a.
