Question

G(x) = x ³ +5x
h(x) = x +5
find g(x) + h(x)

Answer 1

`g(x) + h(x) = x^3 + 6x + 5`

Explanation:

We are told that:

`g(x) = x^3 + 5x`

`h(x) = x + 5`,

and we are asked to find an expression for
`g(x) + h(x)`.

In order to find the expression for
`g(x) + h(x)`, we have to simply add the expressions of
`g(x)` and
`h(x)` together:

`g(x) + h(x)`

=
`x^3 + 5x + x + 5`

=
`x^3 + 6x + 5`
