Factoring GCF Difference of Squares

x² - 5x

• (x - 5)

• (x - 5x)

• (x - 5)

• x²(1 - 5)

What is ALWAYS the first step when factoring?

• Look for the GCF

• Write a, b, and c

• Difference of squares

• Group

Factor 4x²-9

• (4x-9)(4x+9)

• (2x-3)(2x+3)

• 2x-3

• (2x-4.5)(2x+4.5)

Factor
x² + 5x + 4

• (x + 4)(x + 1)

• (x + 2)(x + 2)

• (x + 4)(x - 1)

• (x + 5)(x + 1)

Factor
n²-13n+40

• (n-5)(n-8)

• (n+5)(n-8)

• (n-5)(n+8)

• (n+6)(n+1)

x² - 9

• (x + 3) (x - 3)

• (x - 3) (x - 3)

• (x + 3) (x - 6)
