-2y + 2
Explanation
We have (x - y + 1) - (x + y - 1)
Let’s expand the Parentheses
= x - y + 1 - x - y + 1
Then let’s group the like terms
= (x - x) + (- y - y) + (1 + 1)
= 0 - 2y + 2
= 2y + 2
You have to multiply both of the numbers in the parenthesis and then multiply them again them
Ex: 4 x 4 = 16
(2x2) x (2x2)
4 x 4 =16
