Guiding question:

How are polynomials multiplied?

Multiplying PolynomialsMultiplying Polynomials

To multiply by a monomial use…

distributive property.

To multiply by a binomial use…

the box method,

FOIL, or

the distributive property.

FOIL MethodFOIL Method(2x + 3)(x + 4)

FOIL is an acronym which reminds you to multiply the following terms…

First:

(2x + 3)(x + 4)

Outer:

(2x + 3)(x + 4)

Inner:

(2x + 3)(x + 4)

Last:

(2x + 3)(x + 4)

Distributive Property MethodDistributive Property Method(2x + 3)(x + 4)

Using the distributive property you can distribute the first binomial to the second.

2x(x + 4) + 3(x + 4)

All methods give you the same answer!

As usual, I will not restrict the method you use.

On your HW, disregard the method instructions…just multiply using which ever method you like!

Multiplying by a BinomialMultiplying by a BinomialSimplify (4y – 3)(2y + 2)

Multiplying by a BinomialMultiplying by a BinomialDid you get it?

Simplify:

(a) (4x – 2)(3x – 6)

(b) (3x + 4)(2x + 5)

(c) (6x – 8)(x + 7)

(a) 12x2 – 30x + 12

(b) 6x2 + 23x + 20

(c) 6x2 + 34x – 56

Multiplying by a TrinomialMultiplying by a TrinomialHow would you multiply the following?

(3x2 – 2x + 3)(2x + 7)

You can use the box method, the distributive property method or you can arrange the polynomials vertically and multiply them.

(6n – 8)(2n2 + n + 7)

You can use these methods to multiply polynomials of higher degrees!
