Vedclass · Answer

(B) The quadratic formula for the roots of the equation $ax^2 + bx + c = 0$ is given by $x = \frac{-b \pm \sqrt{D}}{2a}$,where $D = b^2 - 4ac$ is the discriminant.Given that the discriminant $D = 0$,we substitute this into the quadratic formula:$x = \frac{-b \pm \sqrt{0}}{2a}$$x = \frac{-b \pm 0}{2a}$$x = -\frac{b}{2a}$Therefore,when $D = 0$,the quadratic equation has two equal real roots,each equal to $-\frac{b}{2a}$.

If the discriminant $D = 0$,then the roots of the quadratic equation $ax^2 + bx + c = 0$ are ..... .
