For this case we must factor the following polynomial:
[tex]wz-18 + 6z-3w[/tex]
We have two variables, so, the factorization will be of the form:
[tex](w \pm\ ) (z \pm \ )[/tex]
We must find two numbers that when multiplied result in the independent term, that is, -18.
We have to:
[tex]+ 6 * -3 = -18[/tex]
+6 and -3 are used because they are the coefficients that accompany the polynomial variables. So, we have:
[tex](w + 6) (z-3)[/tex]
Answer:
[tex](w + 6) (z-3)[/tex]
