Let f(x) = 2x^2 + 7x - 5 and g(x) = -8x^2 - 3x + 5.

What is g(x) + f(x)?

Sorry to be a burden but I just can't think straight, some help would be appreciated.

set up the question
8x^2-3x+5 + 2x^2 +7x-5
then find like terms
8x^2+2x^2= -6x^2 -3x+7x=4x 5-5=0
so, the answer should be -6x^2 +4x
if not my baddd but I'm 90% sure
