• FOIL

• asking the teacher every time

• assume you're correct

• division

• (x-4)

• (x-8)

• (x+4)

• (x+12)

• (x+5)

• (x+6)

• (x-5)

• (x-30)

Factor (Easy Trinomial)
n² + 16n + 63

• (n-7)(n+4)

• (n+7)(n-9)

• (n-3)(n-10)

• (n+7)(n+9)

Factor (Easy Trinomial)
a² - a - 12

• (a - 4)(a + 3)

• (a + 6)(a - 4)

• (a - 6)(a + 4)

• (a + 4)(a - 3)

Factor: (Easy Trinomial)
