Example

3(r+2s)=2t-4
a⋅(b-2)=3b
3(r+2s)=2t-4
a⋅(b-2)=3b

Question

$$8m(x-y)-16m(x+y)=$$

Answer

-8*m*x-24*m*y

Solution


Expand by distributing terms.
\[8mx-8my-16m(x+y)\]
Expand by distributing terms.
\[8mx-8my-(16mx+16my)\]
Remove parentheses.
\[8mx-8my-16mx-16my\]
Collect like terms.
\[(8mx-16mx)+(-8my-16my)\]
Simplify.
\[-8mx-24my\]
