F(x)=3x^2+7x and g(x)=2x^2-x-1 find (f+g)(x)

(f+g)(x) is .

Step-by-step explanation:

Here we have , f(x)=3x^2+7x and g(x)=2x^2-x-1 or . We need to find (f+g)(x) :

We know that (f+g)(x) = f(x)+g(x) as sum of functions is equivalent to normal addition in Arithmetic . Let's find out (f+g)(x):

Therefore, f(x)=3x^2+7x and g(x)=2x^2-x-1 or and (f+g)(x) is .
