Question

Solve using the zero factor property
(w-4)(w-4)=0

Answer 1

what is the zero factor property?

Answer 2

w = 4 only

Answer 3

Zero Product Property
ab = 0

Answer 4

But what you want to do in this case is the following steps:

(w-4)(w-4) = 0
(w-4)^2 = 0
w - 4 = 0 (after square rooting both sides)

w = 4

Answer 5
