take out the common factor of (x + y) and you end up with (3 + a). Multiply out to check answer.
(x + y)(3 + a)=
3x + 3y + ax + ay=
3(x+y) + a(x+y)

3(x+y) + a(x+y)
(x+y)(3+a)
Once you identified the common factor you get it.
(^-^) = Happy face
3(^-^) + a(^-^)
Common factor above is (^-^)
then factoring is
(^-^) (3+a)
Always think what does the equation have in common
Hope it helps!

they both have the GCF of (x+y)
take out x+y
(x+y) (3+a)
