Best ResponseYou've already chosen the best response.1so ill do one (x^5 + 7x^3  9) + (4x^5  2x^3 + 13) (1)break brackets.. in this case it's easy just remove them but if you had a negative sign infront of the bracket you need to change signs for everything inside that bracket eg (13+5) = 1+35 (2) collect like terms .. group terms so you can visualize which ones are able to be added up. Since you can only add variables (in this case, "x") together when they're raised to the same power. e.g. x^2 +x^4 + 3x^2 +x^8 x^2 + 3x^2 + x^4 +x^8 = 4x^2 + x^4 + x^8 (3) write in increasing order of power

Best ResponseYou've already chosen the best response.1wait i forgot to do it =(x^5 + 7x^3  9) + (4x^5  2x^3 + 13) =x^5 + 7x^3  9 + 4x^5  2x^3 + 13 = 7x^3 2x^3+ x^5+ 4x^5 + 13 = 5x^3 + 5x^5 +13
