SOLUTION: THe instructions say divide. The problem itself is (4x-4 / x) / (10x-10 / 7x^2). I have come up with 28x^2(x-1) / 10x(x-1). Can anyone please tell me if this is the correct answer.

Divide:
%28%284x-4%29%2Fx%29%2F%28%2810x-10%29%2F7x%5E2%29 Recall..."invert the 2nd fraction and multiply"?
%28%284x-4%29%2Fx%29%2A%28%287x%5E2%29%2F%2810x-10%29%29 Simplify.
%284%28x-1%29%2Fx%29%2A%28%287x%5E2%29%2F10%28x-1%29%29 Cancel the common factors: (x) and (x-1)
4%2A7x%2F10 Simplify.
14x%2F5
