\n" ); document.write( "\"%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\r
