Simplify the following expression:

• 
• 
• 
• 

Expand (x + 2)³

• x³ + 6x² - 12x + 8

• x³ + 6x² + 12x + 8

• x³ - 6x² + 12x - 8

• x³ + 4x² + 12x + 6

p(x) = 3x + 4
q(x) = 2x²
Find q(p(x))

• 6x² + 4

• 18x² + 48x + 32

• 18x² + 32

• None of these.

Simplify: (v² - v - 56) ÷ (v - 8)

• (v + 8)

• (v - 7)

• v - 8 R(0)

• v + 7

Solve by factoring.

x² - 3x - 28 = 0

• x = -4

• x = -2, 8

• x = -4, 7

• x = 6, -7
