Intro to Factoring

Factor out the GCF:
10x³ - 15x

• x(10x² - 15)

• 5x(2x² - 3)

• 5(2x³ - 3x)

• 5x²(10x - 3)

Factor using GCF or monomial factoring:

2x + 18

• 2(x + 9)

• 2(x + 8)

• 2(2x + 9)

• cannot be factored

Factor:
2x² + 11x + 14

• (x + 7)(2x + 2)

• (x + 2)(2x + 7)

• (x + 14)(2x + 1)

• (x + 1)(2x + 14)
