Question

Consider the following expression-2m(m+n-4)+5(-2m+2n)+n(m+4n-5)

Answer 1

Answer:-2m^2 + 4n^2 - mn -2m +5n

Step-by-step explanation:

Answer 2

$-2m(m+n-4)+5(-2m+2n)+n(m+4n-5)$

$-2m^2-2mn+8m -10m+10n+mn+4n^2-5n$

Combine like terms.

$-2m^2-mn-2m+5n+4n^2$

Simplify the expression from least to greatest.

$-2m^2 + 4n^2-mn-2m+5n$ is the answer.
