What is the factored form of x2x-2?

2(x-1)(x+1)

Step-by-step explanation:

x2x-2

=2(x^2-1)

=2(x-1)(x+1)

First you  would take 9 x 4 because there is four sides to a 3D piece of wood and then you would add the two 1's x 2 because you have two ends of 1 square inch each then, you would take the 5 and multiply it by 4 because you have four sides to a 3D piece of wood and add the two 1's x 2  because you have two ends of 1 square inch each  and then add all of it together and you have your answer so it should look something like this ... 9 x 4 +2 +2 + 5 x 4 +2 + 2 = a total of 64 inches
