Question

What are two ways you could represent the expression 3-4n

Answer 1

There are not just "the two ways" to represent this expression. There are two ways, surely, but they are not the only ways as implied.

You could expose 4 and get something like
`4((3)/(4)-n)` or expose 3 and get something like
`3(1-(4)/(3)n)`.

But you could also say something like
`3-(1+3)n=3-n-3n=-3(n-1)-n`... in fact there are a lot of ways to write any expression.

Hope this helps :)
