Question

URGET PLEASE HELP

Let f(x) = 5x4 – 2x2 – 8x + 3 and g(x) =
-7x4 + 6x3 + 10x²
x + 4. What is f(x) + g(x)?

Answer 1

f(x)+ g(x) =
`-2x^(4) + 6x^(3) +8x^(2) -8x+3`

Explanation:

You just have to add the like terms separately,

5-7 in
`x^(4)`

only 6 in
`x^(3)`

10-2 in
`x^(2)`

-8 in x

and 3 as the constant
