Answer:
(x+y) (z+1)
Step-by-step explanation:
xz + x + yz + y
- group the first two terms and the last two terms.
(xz + x ) + yz + y
- factor out the greatest common factor (GCF) from each group.
x (z + 1) + y (z + 1)
- factor the polynomial by factoring out the greatest common factor, z + 1.
(x+y) (z+1)
