Review: Factoring Polynomials

Factor 12x - 40 using the GCF

• 2 (6x -20)

• 4 (3x + 10)

• 4 (3x - 10)

• 2 (6x + 20)

Factor out the GCF

4a³b⁵ - 18a²b³ + 8a³b³

• 4a²b³ (ab² - 4 + 2a)

• 2a²b³ (2ab² - 9 + 4a)

• 2a²b³ (2ab - 9ab + 4)

• a²b (4ab - 18a²b³ + 8ab²)

9x² - 49y⁶

• ( 3x + 7y³) (3x + 7y³) 
• ( 3x - 7y³) (3x + 7y³) 
• ( 3x - 7y³) (3x - 7y³) 
• Prime

Factor Completely.  
8x³ - 18x

• 2x(4x²-9)                                    
• (4x²+3)(2x-3)
• 2x(2x+3)(2x-3)
• PRIME

Factor:

a² − a − 12

• (a − 4)(a + 3)

• (a + 6)(a − 4)

• (a − 6)(a + 4)

• (a + 4)(a − 3)

Factor:

n² + 16n + 63

• (n − 7)(n + 4)

• (n + 7)(n − 9)

• (n − 3)(n − 10)

• (n + 7)(n + 9)

Factor Completely:

2c² + 2c - 84

Hint: Factor GCF first.

• (c-6)(2c+14)

• (c+7)(2x-12)

• (c-4)(2c+21)

• 2(c+7)(c-6)

Factor completely: 
3x² + 18x +15
Hint: Factor GCF first.

• 3(x² + 6x + 5)
• (x + 5)(x + 1)
• 3(x + 5)(x + 1)
• Prime
