How do you do this problem ?

Question

Factor out the GCF from the polynomial.
pq(p - 7) + (p - 7)

(p^2q - 7pq) + (p - 7)
pq(p - 7)
(p - 7)(pq + 1)
(p - 7)(pq - 1)

Answer 1

pq(p - 7) + (p - 7)

(p-7) is it

(p-7)(pq + 1)

Answer 2

there are 2 terms, pq(p - 7) and (p - 7). factor out the (p - 7), leaving pq in the 1st term and 1 (always a factor) in the second. so

pq(p - 7) + (p - 7) = (pq + 1)(p - 7)

which is the 3rd answer.
