Module 3 Honors Math 2 Review

• y = 9x² - 15x + 21

• y = -3x² - 75x - 4

• y = 9x² + 90x + 221

• y = -3x² - 30x - 79

• y = -5x² - 20x - 30

• y = -5x² - 4x - 10

• y = 25x² + 100x + 90

• y = 25x² - 10x - 30

Convert to vertex form.

• y=3(x+1)² - 8
• y=3(x-1) ² - 8
• y=3(x+2)² - 8
• y=3(x-2)² - 8

Convert to vertex form.

• y=4(x+4)² - 62
• y=4(x-4)² - 62
• y=4(x-8)² - 62
• y=4(x+8)² - 62

Factor:
 x² – 5x – 24

• (x - 5)(x + 19)
• (x - 8)(x + 3)
• (x - 3)(x + 8)
• (x - 19)(x + 5)

Factor:
 x² + 2x – 3

• (x - 2)(x + 1)
• (x + 1)(x - 3)
• (x + 2)(x - 1)
• (x - 1)(x + 3)

Factor:
 3x²-17x+10

• (x-5)(3x-2)
• (x+5)(3x+2)
• (3x-5)(x-2)
• (x+5)(3x-2)

Solve by factoring.

b² + 2b - 24 = 0 (hint: find the zeros) FACTOR!

• x = 6 or x = -4

• x = -6 or x = -4

• x = 6 or x = 4

• x = -6 or x = 4
