Is there more than one answer possible?

I got 2 answers:

1. (2q+10)(q+6)

2. (2q+12)(q+5)

**RickP**, Tuesday, May 5, 2009 at 11:26pmYou should factor out the GCF.

2q^2 + 22q = -60

2q^2 + 22q + 60 = 0

2(q^2 + 11q + 30) = 0

now divide both sides by 2

q^2 + 11q + 30 = 0

(q + 6)(q + 5) = 0

if 2 numbers multiplied together = 0 then one or both factors must be 0.

q + 6 = 0 and/or q + 5 = 0

q = -6 and/or q = -5

Plug in the 2 possible answers and see if one or both of them work.
