# Find the roots of each of the following equations, if they exist, by applying the quadratic formula:36x2 – 12ax + (a2 – b2) = 0

Given: 36x2 – 12ax + (a2 – b2) = 0

Comparing with standard quadratic equation Ax2 + Bx + C = 0

A = 36, B = – 12a, C = a2 – b2

Discriminant D = B2 – 4AC

= (– 12a)2 – 4.36.(a2 – b2)

= 144a2 – 144a2 + 144 b2 = 144 b2 > 0

Hence the roots of equation are real.

Roots are given by

Hence the roots of equation are
