Answer:

Step-by-step explanation:
Remember when you divide fractions, you need to get the reciprocal of the divisor and multiply. So your first simplification would be:

Next we factor what we can so we can further simplify the rest of the equation:

We can now cancel out (x+2)

Next we factor out even more:

We cancel out x-4 and reduce the 3 and 6 into simpler terms:

And we can now simplify it to:

You can use the prefixes to figure this out:
Mono: one
Bi: two
Tri: three
So, because there is only one term, it is a monomial.
