Question

Factor out the GCF, then solve the following expression.
2w² - 8w = 0

Answer 1

w = 0, 4

Explanation:

The GCF is 2w

2w (w-4) = 0

w = 0 or 4

Answer 2

w=0,4

Explanation:

2w² - 8w = 0

Each term has a 2 and a w that can be factored out

2*w*w - 4*2*w = 0

2w(w-4) =0

Using the zero product property

2w =0 w-4=0

2w/2 =0/2 w-4+4=0+4

w=0 w=4
