Question

What is the simplified form of the following expression?
`{6}^(2) + 7.2n + 2.5m^(2) - n`

Answer 1

`6m^2+7.2n-4n+2.5m^2-n`

There isn't much to simplify here.

There are 2 n's and 2 m^2's.

We combine like terms.

So, we ccan write them "together" like this:

`6m^2+2.5m^2+7.2n-4n-n`

Simplifying:

`8.5m^2+2.2n`
