Unit 2 and 3 Review

Solve by factoring:  2x²+ 7x + 6 = 0

• x= 3/2 and x = 2
• x = -3/2 and x = -2
• x = 6 and x = 7
• x = -6 and x = -7

Select the values where f(x) = 0. (x - intercepts)

• -2, 1
• 1, 2
• -1,2
• 0,-4

Solve 5x² = 13x+6

• x = -3, x = 2/5

• x = -2, x = 15

• x = 3, x = -2/5

• x = 2, x = -15
