Question

Philoid · Accepted Answer

Given:

taking LCM

3x² – 6x + 2 = 0 cross multiplying

Comparing with standard quadratic equation ax² + bx + c = 0

a = 3, b = – 6, c = 2

Discriminant D = b² – 4ac

= (– 6)² – 4.3.2

= 36 – 24 = 12 > 0

Hence the roots of equation are real.

Roots are given by

Hence the roots of equation are
