Factor completely:
 $x^2-2x-24$  

•  $(x+4)(x-6)$  

•  $(x+4)(x+6)$  

•  $(x+6)(x-1)$  

•  $(x-4)(x+6)$  

Factor completely:
 $3x^2-8x+4$  

•  $(3x-4)(x-1)$  

•  $(3x-2)(x-2)$  

•  $(x+1)(3x+4)$  

•  $(x+2)(3x+2)$  

Solve
6x² + 17x + 12 = 0

• x = -4/3, x = -3/2
• x = 9, x = 8
• x = 4, x = 3
• x = -4, x = -3

Solve
x² + 2x - 24 = 0

• x = -6, x = 4
• x = 6, x = -4
• x = 12, x = -2
• x = 8, x = -3
