Steps:
Let's simplify step-by-step.
9y+2xy−2−4y+4xy+2
=9y+2xy+−2+−4y+4xy+2
Combine Like Terms:
=9y+2xy+−2+−4y+4xy+2
=(2xy+4xy)+(9y+−4y)+(−2+2)
=6xy+5y
Description:
The first step is to simplify the equation step by step and to simplify an equation you can first multiplying the factors and use the exponent rules to remove the parentheses. After that you need to combine it a terms. Then you will get your answer.
