Question

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

Answer 1

-2m(m+n-4)+5(-2m+2n) +n(m+4n-5)
-2m^2-2mn+8m-10m+10n+mn+4n^2-5n
-2m^2+4n^2-2m+5n-mn
Hope this helps!

Answer 2

Hello! And thank you for your question!

First we are going to expand the equation:

−2m^​2​​−2mn+8m−10m+10n+nm+4n​^2​​−5n

Then we are going to combine like terms:

−2m​^2​​+(−2mn+mn)+(8m−10m)+(10n−5n)+4n​^2​​

Then finally, simplify:

−2m​^2​​−mn−2m+5n+4n​^2

Final Answer:

−2m​^2​​−mn−2m+5n+4n​^2
