If x = $\frac{- b + \sqrt{b^{2} - 4 a c}}{2 a}$ , then express the given formula in terms of a.

If b² – 4ac = 0 then The roots of the Quadratic equation ax² + bx + c = 0 are given by :

y = \frac{a x^{2}}{(x - a) (x - b) (x - c)} + \frac{b x}{(x - b) (x - c)} + \frac{c}{x - c} + 1,

\frac{y^{'}}{y}

(Here, y^{'} = \frac{d y}{d x})

a x^{2} + b x + c = 0

x = \frac{- b + \sqrt{b^{2} - 4 a c}}{2 a}

c = - a x^{2} - b x
