Answer 2

Understanding the Expression: (m^2 - n^2 - m + n)

The expression (m^2 - n^2 - m + n) can be simplified using algebraic techniques. Let's break down the expression step by step.

1. Factorization of m^2 - n^2: - The expression m^2 - n^2 can be factorized using the difference of squares formula, which states that a^2 - b^2 = (a + b)(a - b). - Therefore, m^2 - n^2 can be written as (m + n)(m - n).

2. Rearranging the Expression: - After factorization, the expression becomes (m + n)(m - n) - m + n.

3. Combining Like Terms: - We can further simplify the expression by combining like terms. - After rearranging, the expression becomes m^2 - n^2 - m + n.

4. Final Expression: - Therefore, the final simplified expression is (m + n)(m - n) - m + n.

Explanation of the Result:

The result of the expression (m^2 - n^2 - m + n) can be understood as a combination of the difference of squares and the addition/subtraction of the variables m and n.

The specific value of the expression will depend on the values assigned to m and n. If you have specific values for m and n, you can substitute them into the expression to calculate the result.
