Question 225171: _w2_- _1_ (dot) _w_-_1______
(w-1)2 w2 +2w + 1
This is my last one I promise!! the first 2 on top after the w is to the power 2, and there is a dot in between the 2 fractions that means to multiply right or is it just add? Yikes. It has been a while since I have done any math!! :( Anyway the bottom row the 2 after the parenthesis is a to the power too 2 and so is the first one after the w in the bottom second fraction and i think that is it. I am sorry these turn out to be so messy. Thank you.
