Solving the Quadratic Formula

Use the quadratic formula to find the solutions for

y = -x² - 5x + 12

• -4.9 and -0.1

• -8.54 and 8.54

• -0.45 and 3.55

• -6.77 and 1.77

Solve using the quadratic formula.
2x² - 9x - 35 = 0

• x = 7/2, x = -6

• x = -5/2, x =5

• x = -3/7, x =6

• x = -5/2, x = 7

Solve using the Quadratic Formula:
x² + 4x + 3 = 0

• x = 1 and x = 3

• x = 6 and x = -2

• x = -1 and x = -3

Use the quadratic formula to solve: n² = 9n - 20

• n = 4, -5

• n = -4, 5

• n  = -4, -5

• n  = 4, 5
