Question

if the roots of the equation ax^2+bx+c=0 are equal then the value of c is*​

Answer 1

Answer:

$\frac{b^2}{4a}$

Step-by-step explanation:

For the equation to have equal roots, the discriminant must be equal to zero.

D= b² −4ac=0

⇒ b² =4ac

⇒ c=  $\frac{b^2}{4a}$

∴ Option D is correct.
