%28-a%5E2%2B5a-8%29-%28-4a%5E2%2B6a-5%29...I guess you have this; first eliminate parenthesis, be careful if minus sign in front, the rule for the "sign" in front of the parenthesis: the plus sign inside of the parenthesis become a minus (negative) sign and the negative sign become a positive
-a%5E2%2B5a-8%2B4a%5E2-6a%2B5%29
3a%5E2-a-3%29
