- Both the middle term and constant terms are positive, so the factors are both
#x bb(color(red)(+)) c# . - The only factors of
#3# are#1# and#3# . - Because of the way you expand factored quadratics (first, outer, inner, last), the factors of the constant term add together to give the middle term's coefficient when a quadratic is factorable.
Therefore, this becomes
