Solution

We have been given, 3x2 - 2x + 2 = 0

Now we also know that for an equation ax2 + bx + c = 0, the discriminant is given by the following equation:

D = b2 - 4ac

Now, according to the equation given to us, we have,a = 3, b = -2 and c = 2.

Therefore, the discriminant is given as,

D = (-2)2 - 4(3)(2)

= 4 - 24

= -20

Since, in order for a quadratic equation to have real roots, D ≥ 0.Here we find that the equation does not satisfies this condition, hence it does not have real roots.
