please check to see if I have this right.

Divide and simplify to lowest terms.

2x^2-8x/5x-8 x-4/5x-8

Do you know how to use parentheses? I don't know if I should read your problem as written or how I think you intended it to be written. Ex: 5x divided by (x-2) would be written as:

5x/(x-2), not 5x/x-2.
