The answer is (z - 3) (w + 6)

For this case we must factor the following polynomial:


wz-18 + 6z-3w

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


(w \pm\ ) (z \pm \ )

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

We have to:


+ 6 * -3 = -18

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


(w + 6) (z-3)

Answer:


(w + 6) (z-3)
