Question

Factor the binomial completely.
w^3+16w

Answer 1

do you see any terms in common between w^3 and 16w ?

Answer 2

no, i would say the w but they have different powers,.....right

Answer 3

but w^3 is the same as w*w*w, so they do indeed have a single w in common

Answer 4

okay

Answer 5

so you'd factor out the common factor of w

w^3 + 16w = w*(w^2 + 16)

notice how I pulled out the 'w' and I'm writing it off to the left

Answer 6

Yeah

Answer 7
