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.
0 0 = 2x2 – 7x - 9
0 0 = x2 - 4x + 4
0 0 = 4x2 – 3x – 1
0 0 = x2 – 2x – 8
0 0 = 3x2 + 5x + 3
