Exercise 4 Page 527

The acronym FOIL stands for First, Outer, Inner, and Last.

10v^2 - 33v -7

Practice makes perfect

We want to simplify the given product using the FOIL method. Recall that the acronym F OI L stands for First, Outer, Inner, and Last.

Let's now simplify the expression by multiplying and combining like terms.

(2v)(5v) + (2v)(1) + (-7)(5v) + (-7)(1)

(- a)b = - ab

(2v)(5v) + (2v)(1) - 35v -7

a * 1=a

(2v)(5v) + 2v - 35v -7

Multiply

10v^2 + 2v - 35v -7

Subtract terms

10v^2 - 33v -7
