Question

(2-m)*(-m-2)-(25+m²)

Answer 1

(-m +2)*(-m-2) -25-m2
(-m)2 -4-25-m2
m2-4-25-m2
-4-25
-29

Answer 2

Let's simplify the expression:

(2 - m) * (-m - 2) - (25 + m²)

First, let's simplify the product of the two binomials:

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

Now, let's multiply the terms:

-2m - 4 + m² + 2m

Now, let's simplify further by combining like terms:

(-2m + 2m) + (m² - 4)

The terms -2m and 2m cancel each other out, so we're left with:

m² - 4

So, the simplified expression is:

m² - 4
