Factoring Practice

What is the GCF of 18k and 15k³

• 3k²
• 3k³
• 3k
• 5k

What is the GCF of 18 and 24?

• 3

• 6

• 8

• 9

What is the GCF? 3x²-2x

• 3
• 3x
• x
• 2

Factor:
10x + 15

• 100x + 150
• 10(x + 5)
• 1(10x + 15)
• 5(2x + 3)

Factor:
x² - 5x

• 1(x - 5)
• x(x - 5x)
• x(x - 5)
• x²(1 - 5)

Factor by using GCF:
8n³ + 2n²

• 2n²(4n-1)
• 2n²(4n + 1)
• n²(8n+2)
• 3n(4n+1)

Factor out the GCF

3x³ + 9x

• 3x (x² + 3)

• 3x ( x³ + 9)

• x (3x² + 9)

• 3x (x³ + 3x)

Factor completely

18x³ + 81x - 27

• 9x (2x² + 9x - 3)

• 3 (6x³ + 27x - 9)

• 9 (2x³ + 9x - 3)

• 9 (2x² + 9x - 3)

Factor:
56a³-8a

• 8a²(56a³-8a)
• 8a(7a²-1)
• 8a(7a³-a)
• 8a²(35a²-a)

Factor:

2n²-8n³

• 2n²(n-4n²)

• -2n²(4n²-1)

• 2n³(10-8n²)

• 3n(1-4n)
