Question

Remove the parentheses from the following expression, and combine like terms.
2x(y-z) + x(y+z)

Answer 1

2x(y-z)+x(y+z)
2xy-2xz+xy+xz
like terms.(2xy+xy=3xy)(-2xz+xz=-xz)
=3xy-xz

Answer 2

simplified form of the given expression is (3xy - xz)

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
