Question

Let f(x)=x^2+5 and g(x)=x^2+8. Find the following functions, and simplify each as much as possible: your final answer should be a polynomial with only one term in each power of x.

f(x)+g(x)=

f(x)−g(x)=

f(x)g(x)

f(x)/g(x)=

Answer 1

1) 2x^2+13
2)-3
3)\[x ^{4}+13x ^{2}+40\]
4)\[(x^2+5)/(x^2+8)\]

Answer 2

for the last one u have to factor both equations
