Substitute the values for a, b, and c into b2 – 4ac to determine the discriminant. Which quadratic equations will have two real number solutions? (The related quadratic function will have two x-intercepts.) Check all that apply.

A. 0 = 2x2 – 7x – 9
B. 0 = x2 – 4x + 4
C. 0 = 4x2 – 3x – 1
D. 0 = x2 – 2x – 8
E. 0 = 3x2 + 5x + 3

A. 0 = 2x2 – 7x – 9

C. 0 = 4x2 – 3x – 1

D. 0 = x2 – 2x – 8

What are quadratic equations and examples?

In a quadratic equation, the variable x is an unknown value, for which we need to find the solution. Examples of quadratic equations are: 6x² + 11x – 35 = 0, 2x² – 4x – 2 = 0, 2x² – 64 = 0, x² – 16 = 0, x² – 7x = 0, 2x² + 8x = 0 etc.
