=3xy-xz
Answer:
simplified form of the given expression is (3xy - xz)
Step-by-step explanation:
The given expression is 2x(y - z) + x(y + z)
We have to remove the parenthesis first
2x(y - z) + x(y + z) = 2xy - 2xz + xy + xz
Now we will collect the similar terms
= 2xy + xy + xz - 2xz
= 3xy - xz
Therefore, simplified form of the given expression is 3xy - xz
