Factor Quadratics

Factor: x²+16x+64
WHAT TWO NUMBERS MULTIPLY TO 64
AND ADD UP TO 16? 

• (x+8)(x+8)
• (x+2)(x+32)

Factor x² + 12x + 20
WHAT TWO NUMBERS MULTIPLY TO 20
AND ADD UP TO 12? 

• (x + 2)(x + 10)
• (x + 7)(x + 5)
• (x + 6)(x + 6)

Solve by factoring: x² - 9x + 20 = 0

• x = -4 and x = -5
• x = 20 and x = -9
• x = 4 and x = 5
• x = -4 and x = 5
