Question

a x square + bx + c is equal to zero has equal roots then value of C is equals to​

Answer 1

Answer:

Step-by-step explanation:

ax2 + bx + c =0,

for equal roots b2 - 4ac=0,

therefor c=b2/4a

Answer 2

The value of c is $c=\dfrac{b^2}{4a}$.

Step-by-step explanation:

Consider a quadratic equation is defined as

$ax^2+bx+c=0$

If $b^2-4ac=0$,then this equation have two equal roots.

We need to find the value of c if the given equation have equal roots.

$b^2-4ac=0$

$b^2=4ac$

Divide both sides by 4a.

$\dfrac{b^2}{4a}=c$

Therefore, the value of c is $c=\dfrac{b^2}{4a}$.
