Question

If one side of a square measures (3x - 8)ft., find the area of the square show work

Answer 1

`9x^(2)`-48x+64

Explanation:

First, start off with what the area would look like with the equation plugged in.

`(3x-8)x^(2)`=area -----> (3x-8)(3x-8)

Second, multiply out the numbers in the ()s.

(3x-8)(3x-8) ---> (3x)(3x) =
`9x^(2)` --->(3x)(-8)=-24x----->(-8)(3x)=-24x------>(-8)(-8) = 64

Finally, you combine like terms and you have your answer.

`9x^(2)`-24x-24x+64 ----->
`9x^(2)`-48x+64

Hoped this helped!
