Factoring Review Algebra

What is ALWAYS the first step when factoring?

• Look for the GCF

• Write a, b, and c

• Difference of squares

• Group

Factor:

x² + 9x + 20

• (x + 4)(x + 5)

• (x + 20)(x + 1)

• (x + 10)(x + 2)

• PRIME

Factor
x² -16x + 48

• (x - 12)(x - 4)
• (x + 6)(x - 8)
• (x + 12)(x - 4)
• (x -16)(x - 3)

Factor:
x² + 7x - 30

• (x + 10)(x - 7)
• (x - 10)(x + 3)
• (x + 10)(x + 3)
• (x + 10)(x - 3)

Factor
a² - a - 12

• (a - 4)(a + 3)
• (a + 6)(a - 4)
• (a - 6)(a + 4)
• (a + 4)(a - 3)

Factor:
v² + 3v - 88

• (v + 11)(v - 8)
• (v + 22)(v - 4)
• (v + 8)(v - 11)
• (v - 22)(v + 4)

Factor:
