Question

Solve the equation 2x² + x + 1 = 0

Answer 1

The given quadratic equation is 2x² + x + 1 = 0

On comparing the given equation with ax² + bx + c = 0, we obtain

a = 2, b = 1, and c = 1

Therefore, the discriminant of the given equation is

D = b² – 4ac = 1² – 4 × 2 × 1 = 1 – 8 = –7

Therefore, the required solutions are
