Hello! And thank you for your question!

First we are going to expand the equation:

<span>−2<span>m^<span><span>​2</span><span>​​</span></span></span>−2mn+8m−10m+10n+nm+4<span>n<span><span>​^2</span><span>​​</span></span></span>−5n

Then we are going to combine like terms:

</span><span><span>−2<span>m<span><span>​^2</span><span>​​</span></span></span>+(−2mn+mn)+(8m−10m)+(10n−5n)+4<span>n<span><span>​^2</span><span>​​</span></span></span></span>
</span>
Then finally, simplify:

−2<span>m<span><span>​^2</span><span>​​</span></span></span>−mn−2m+5n+4<span>n<span>​^<span>2

Final Answer:
</span></span></span>
−2m​^2​​−mn−2m+5n+4n​^2

In the two digit number x,both the sum and the difference of its digit is 6. What is the value of x ?
Levart [38]
Let a be the first digit and b the second. Then the number is x=10a+b. The sum and difference of the two digits is 6, which means

\begin{cases}a+b=6\\a-b=6\end{cases}\implies a=6,b=0

which means the number is x=6\times10+0=60
