Reviewing the "Box Method"

Last week we learned the box method of multiplying polynomials...

binomial by binomial

Today: We are going to see how to multiply larger polynomials using two methods.

Multiple Choice

Let's try!

(2x+1) (x+1)

Multiply the binomials.

$2x^{2\ }+\ 2x+x+1$

$2x^2+3x+1$

$3x^2+3x+1$

Multiple Choice

$\left(2x^2+x+5\right)\cdot\left(x+1\right)$ Choose the box that represents the situation.

Multiple Choice

$\left(2x^2+x+5\right)\cdot\left(x+1\right)$ Choose the correct equation.

2 $3x^3+2x^2+5x+5$

$2x^3+3x^2+6x+5$

$2x^3+2x^2+6x+5$

Use the distributive property to multiply each term from the first by each term on the second polynomial.

Find an example of multplying a binomial by trinomial. Using the boxmethod or distributive method solve that problem.
