Q. 20
Find the roots of each of the following equations, if they exist, by applying the quadratic formula:
3x2 – 2x + 2 = 0
Answer :
Given: 3x2 – 2x + 2 = 0
Comparing with standard quadratic equation ax2 + bx + c = 0
a = 3, b = – 2, c = 2
Discriminant D = b2 – 4ac
= (– 2)2 – 4.3.2
= 4 – 24 = – 20 < 0
Hence the roots of equation do not exist
