Answer:
Factors are (x +y) ( z +1) .
Step-by-step explanation:
Given : xz + x + yz + y
To find : Factor the four-term polynomial.
Solution : We have given xz + x + yz + y
Taking x common from first two terms and y from last two terms
x ( z + 1) + y( z + 1) .
On grouping
(x +y) ( z +1) .
Therefore, Factors are (x +y) ( z +1) .
