Factoring GCF and Simple Trinomials

Factor the trinomial.

• (x+9)(x-8)

• (x-9)(x+8)

• (x+72)(x-1)

• (x-72)(x+1)

Factor the trinomial.

• 4(x+3)(x-1)

• (x-4)(x+1)

• 4(x+4)(x-1)

• 4(x-4)(x+1)

Solve by factoring: x² - 9x + 20 = 0

• x = -4 and x = -5

• x = 20 and x = -9

• x = 4 and x = 5

• x = -4 and x = 5
