Question

Use the FOIL Method to find (w+9)(w+6)

Answer 1

Answer: w^2 + 15w + 54

Explanation:

FOIL = first, outside, inside, last.

First —> multiply first numbers of each parentheses.

Outside —> multiple the OUTSIDE numbers in each parentheses (first number in the first parentheses, second number in the second parentheses.

Inside —> multiply the INSIDE numbers in each parentheses (the second number in the first parentheses, first number in the second parentheses).

Last —> multiply second number of each parentheses.

(W + 9)(w + 6)

F = w^2

O = 6w

I = 9w

L = 54

W^2 + 6w + 9w + 54

W^2 +15w + 54

Answer 2

Explanation:

First, outside, inside, last.

w*w

6*w

9*w

9*6

`w^2+15w+54`
