Factor the polynomial:
wz -18 +6z -3w

For this case we must factor the following polynomial:

We have two variables, so, the factorization will be of the form:

We must find two numbers that when multiplied result in the independent term, that is, -18.

We have to:

+6 and -3 are used because they are the coefficients that accompany the polynomial variables. So, we have:

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
