Answer 2

To simplify the expression (2+m)²(2-m)², you can use the formula for the difference of squares, which states that (a + b)(a - b) = a² - b².

So, applying the formula:

(2 + m)²(2 - m)² = (2 + m)² - (2 - m)²

Now, let's expand both terms:

(2 + m)² = (2 + m)(2 + m) = 2(2) + 2m + m(2) + m² = 4 + 4m + m²

(2 - m)² = (2 - m)(2 - m) = 2(2) - 2m - m(2) + m² = 4 - 2m + m²

Now, we can substitute these back into the original expression:

(2 + m)²(2 - m)² = (4 + 4m + m²) - (4 - 2m + m²)

Now, distribute the negative sign:

(2 + m)²(2 - m)² = 4 + 4m + m² - 4 + 2m - m²

Combine like terms:

(2 + m)²(2 - m)² = 6m + 2

So, the simplified expression is 6m + 2.
