Question

I need an explanation please​

Answer 1

Answer: 2n - 2

===================================================

Step-by-step explanation:

The
`n^2` terms cancel out because

`n^2 + (-n^2) = n^2 - n^2 = 0n^2 = 0`

The n terms combine to

5n + (-3n) = 5n - 3n = 2n

Lastly, the constants combine to

-6 + 4 = -2

Overall we have 2n - 2 as the simplified result.
