Question

Roots of a Quadratic Equation.

Answer 1

Roots of a Quadratic Equation : The value of $x$ (say $x=\alpha, \beta$ ) which satisfy the quadratic equation are called the roots of the equation and they are given by

$\alpha=\frac{-b+\sqrt{b^2-4 a c}}{2 a}, \quad \beta=\frac{-b-\sqrt{b^2-4 a c}}{2 a}$
