Use the caret (^) to denote exponents, 4x^2=4x%5E2.

Gather like terms,
-5x%2B8-4x%5E2-4x%2B2x%5E2=%28-5x-4x%29%2B%288%29%2B%28-4x%5E2%2B2x%5E2%29
-5x%2B8-4x%5E2-4x%2B2x%5E2=x%28-5-4%29%2B%288%29%2Bx%5E2%28-4%2B2%29
-5x%2B8-4x%5E2-4x%2B2x%5E2=x%28-9%29%2B%288%29%2Bx%5E2%28-2%29
Rewrite with terms of x in descending order of exponents.
-5x%2B8-4x%5E2-4x%2B2x%5E2=highlight%28-2x%5E2-9x%2B8%29
