Hello can you check to see if am doing this right please

Answer 1

we are given the following polynomials:

`\begin{gathered} -6n+3 \\ 4n-9 \end{gathered}`

Adding the two expressions we get:

`(-6n+3)+(4n-9)`

Associating like terms, that is, terms that have the same variable elevated to the same number we get:

`(-6n+4n)+(3-9)`

Adding like terms:

`-2n-6`

An thus we get the sum of the expressions.
