Question

You are painting a rectangular wall with length 5X to the second power seat and with 12 X feet. There is a rectangular door that measures X feet by 2 feet that will not be painted. What is the area of the wall that is to be painted? Write your answer in factored form

Answer 1

Answer:

It looks like you need to find the area of the wall and subtract the area of the door

(5x2 ∗ 12x) - (x ∗2x)

Simplify each term in the parentheses  

60x3 - 2x2

Then we can factor that expression using the greatest common factor.

The GCF is 2x2 so we divide both terms by 2x2

2x2(30x - 1)
