Question

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

Answer 1

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

Answer 2

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:

$(w + 6) (z-3)$
