Answer 5

yes is this try solve it for medal - i will give you - ok. ?

Answer 6

if you add them together you would end up with 3x^2+x+1

Answer 8

exactly but please write it step by step for the Asker can understanding it easy sure - ok. ?

Answer 9

in this way

f(x)+g(x) = (f+)(x) = ?

Answer 10

i missed the g from there - sorry

Answer 11

(f+g)(x)

Answer 12

So you have f(x)= 3x^2-1 and g(x)= x+2. since it is asking you to add them, you would have 3x^2-1+x+2. Then, you simplify so you would end up with the answer which is 3x^2+x+1.
