Question

Determine the discriminant for the quadratic equation –3 = x2 + 4x + 1. Based on the discriminant value, how many real number solutions does the equation have?

Discriminant = b2 – 4ac

Answer 1

Hey MATE!!!

To find Discriminant we first make the equation in proper form;

x^2 +4x +1 = -3

=>x^2 +4x +4 = 0

Hence, D = 4^2 - 4(1)(4)

=> 16 - 16 = 0

Since, D = 0 Therefore the roots of the equation exists and are equal.

Hope it helps
