Answer 2

It looks like you have an expression with variables a, b, m, and n. Let's simplify this expression step by step:

Expression: 3a + 7b(m-n)² - 4a - 2b(m-n)² + 8a + 6b(m-n)²

Step 1: Group like terms together: (3a - 4a + 8a) + (7b - 2b + 6b)(m-n)²

Step 2: Simplify the coefficients of 'a': 7a + (7b - 2b + 6b)(m-n)²

Step 3: Simplify the coefficients of 'b': 7a + 11b(m-n)²

So, the simplified expression is:

7a + 11b(m-n)²
