Question

which of the following equation has two distinct real roots?​

Answer 1

Answer:

A quadratic equation, ax2 + bx + c = 0; a ≠ 0 will have two distinct real roots if its discriminant, D = b2 - 4ac > 0. Hence, the equation x2 –3x + 4 = 0 has no real roots. Hence, the equation 2x2 + x – 1 = 0 has two distinct real roots.
