Factor

x² + 18x + 81                      

• (x + 9)(x – 9)

• (x + 18)²

• (x + 9)²

• (x + 6)²

Find the product:
(3x – 1)(x + 5) 

• 3x² + 4x + 5

• 3x² + 4x - 5

• 3x² + 14x + 5

• 3x² + 14x - 5

Factor by using the GCF:

x² - 14x

• x(x - 14x)

• 2x(x - 7)

• x²(x - 14)

• x(x - 14)

Factor by GCF:

6x² + 16x

• 2(3x² + 8x)

• 2x(3x + 8)

• 2x(3x + 8x)

• not factorable

Factor using the GCF : -21x+35

• -7(3x - 5)

• 7(-21x² + 35)
