Answer:

x = $\frac{1}{2}$ , -1

Step-by-step explanation:

The quadratic formula is: -b±√b²-4ac

The discriminant (Δ) is b²-4ac. Evaluating this expression after substituting for a, b and c helps you identify the number of real solutions to the quadratic equation.

a = 2, b = 3, c = 1

Δ = -3²- 4 x 2 x 1;

Δ = 1
