Answer 2

Answer :

Given Condition

$\large{ \sf{b {}^{2} - 4ac = 0 }}$

Here,as the discriminant of the given equation is zero. Its roots would be real and equal

To find:

Roots of the equation ax² + bx + c = 0

Applying the Quadratic Formula,

$\sf{x = \frac{ - b \pm \sqrt{b {}^{2} - 4ac } }{2a} } \\ \\ \implies \: \underline{\boxed{\sf{x = \frac{-b}{2a} }}}$

Thus,the roots of the equation would be -b/2a and -b/2a
