%286x-5y%29-%288x%2B2y%29
Multiply through the -1:
6x-5y-8x-2y
Combine like terms:
highlight%28-2x-7y%29
----------------------
9%28x%2B1%29-5%28x%2B1%29
9x%2B9-5x-5
4x%2B4
You can factor this:
highlight%284%28x%2B1%29%29
----------------------
4x-3%28x-4%29%2B6%28x-4%29
4x-3x%2B12%2B6x-24
highlight%287x-12%29
=================
Good Luck,
