(7x^3+2x^2-3) + (5x^3-8x^2+4x+5) is the answer 12x^3+10^2+2

you did not end up with the correct result ... 2-9 is not 10, and you lost a term along the way

OpenStudy (amistre64):

it helps me to stack them so that i line up the like terms; adding just means to combine them together. 5 + (-3) is still adding, but it amounts to 5-3 7x^3 +2x^2 -3 +5x^3 -8x^2 +4x +5 -------------------

12x^3-6x^2+4x+2
