Let f(x)=2x^2+7x-5 and g(x)=-8x^2-3x+5 what is g(x)+f(x)
Answers: 2
![g(x)+f(x)=-8x^2-3x+5+2x^2+7x-5\\\\\Rightarrow\ g(x)+f(x)=-8x^2+2x^2-3x+7x+5-5.............[\text{Combing like terms}]\\\\\Rightarrow\ g(x)+f(x)=(-8+2)x^2+(-3+7)x+0.................\text{[Adding coefficients of like terms]}\\\\\Rightarrow\ g(x)+f(x)=-6x^2+4x](/tpl/images/0274/9486/01e05.png)
