### 7-6 Using the quadratic formula

ALGEBRA 1 CP

• Solve 3x2 = 48.

• Solve x2 + 5x + 6 = 0 by using the quadratic formula.

• Solve 2x2 + 3x - 2 = 0 by using the quadratic formula.

• Solve 4x + 2x2 - 7 = 0 by using the quadratic formula. Round solutions to the nearest hundredth.

• Solve 3 - 3x2 + 4x = 0 by using the quadratic formula. Round solutions to the nearest hundredth.

• Pg346 – 347 # 7 – 18 even, 20
