Okay, so let's see...
OpenStudy (liv1234):
I know what the answer is (3x-2)(3x+2), but I need the steps aha
OpenStudy (haleyelizabeth2017):

You can put the answer and then checking your work?
OpenStudy (haleyelizabeth2017):
Think that would work?
OpenStudy (haleyelizabeth2017):
Well, explain that 3x times 3x is 9x^2, and 2*-2 is -4...
OpenStudy (liv1234):
Ohh okay, that makes sense haha
OpenStudy (haleyelizabeth2017):
and that 18x-18x is 0, so we leave that out. Which leaves us with (3x-2)(3x+2)
