Question 30072: Please assist me in solving this problem. I think I am suppose to group like terms, but I am really confused.
(5x^6 - 6x^5 - 9x^4 - 2) - (7x^6 + 4x^5 - 3x^4 - 3)

since the second term is preceeded by a negative, change all the signs in the second quantity and drop the parenthesis
combine x^6
combine x^5
combine x^4
combine constants
since there is no = , this is a simpliflying problem

(5x^6 - 6x^5 - 9x^4 - 2) - (7x^6 + 4x^5 - 3x^4 - 3)
yes, group like terms
first do the subtraction
(5x^6 - 6x^5 - 9x^4 - 2) - 7x^6 - 4x^5 + 3x^4 + 3
now group like terms
(5x^6 - 7x^6) + (-6x^5 - 4x^5) + (-9x^4 +3x^4) + (-2 + 3)
now combine terms
-2x^6 -10x^5 - 6x^4 +1
