Answer

Comparing equation 2x2 - 3x + 1 = 0, with ax2 + bx + c = 0, we get :

a = 2, b = -3 and c = 1.

By formula,

D = b2 - 4ac

= (-3)2 - 4 × 2 × 1

= 9 - 8

= 1; which is positive.

Since, a, b and c are real numbers; a ≠ 0 and b2 - 4ac > 0

∴ Roots are real and unequal.

Hence, Option 1 is the correct option.
