Factoring Using Gcf Practice

Factor 7x + 21 using the GCF

• 7(x+3)

• 7x + 3

• 3(x + 7)

• x(7 + 3)

Factor -9x + 33 using the GCF

• -3 (3x - 11)

• -9 (x + 4)

• 3 (3x + 11)

• 9 ( -x + 4)

Factor by using GCF:

10x² + 15x - 5

• 25(10x³ + 45x - 15)

• 5(2x³ + 3x² - x)

• x(10x³ + 15x - 5)

• 5(2x² + 3x - 1)

Factor out the GCF:
10x³ - 15x

• x(10x² - 15)

• 5x(2x² - 3)

• 5(2x³ - 3x)

• 5x²(10x - 3)

Factor by GCF:
10x² + 15x - 5

• 25(10x³+45x-15)

• 5(2x³ + 3x²-x)

• x(10x³+15x-5)

• 5(2x²+3x-1)
