First, we expand the expression:
(a + 2b - (a + b))^2(a + 2b - a - b)^2(2b)^24b^2
Therefore, the expression (a + 2b - (a + b))^2 simplifies to 4b^2.
First, we expand the expression:
(a + 2b - (a + b))^2
(a + 2b - a - b)^2
(2b)^2
4b^2
Therefore, the expression (a + 2b - (a + b))^2 simplifies to 4b^2.
