Question

Hi jiskha! I was wondering if anyone could answer this ~fun~ question. f(x)=5x^2-2x+3 and g(x)=4x^2+7x-5. I have to find f+g. For my answer, I got 12x^4+-2x+-2, while the answers in my packet said 9x^2+5x-2. Could anyone explain this? (Unless I wrote down the wrong answer in my packet originally) Thank you!! :)
