How to Multiply Binomials

Multiply: (x + 5)(x + 4)

• x² + x + 20

• x² + 20x + 9

• x² + 9x + 20

• x² - 9x + 54

You can FOIL to multiply polynomials...

• When you have 2 binomials

• Any time

• When you have a monomial

• When you have only 1 binomial

(x - 4)(x - 6)

• x² -10x + 24

• x² - 10x - 24

• x² +10x + 24

• x² + 10x - 24

Find the product:
(x + 12)(x - 12)

• x² - 144

• x² + 144

• x² + 12x - 144

• x² - 12x + 144

(x+7)(x−7)

• x²−14x−49

• x²−49

• x²+49

• x²+14x−49

(3x – 1)(x + 5) 

• 3x² + 4x + 5
