14m+6m+514m+6m+5

Explanation:

So first you should realize that there is -1 1 infront of the parentheses. Let's write that out.

14m-1(-6m-5)14m1(6m5)

Now use -11 to expand the parentheses using the distributive property.

-1(-6m-5)1(6m5)

Remember;

+*+=+++=+

-*- =+=+

-*+=-+=

So -1*-6m=+6m16m=+6m and -1*-5=+515=+5

:. we have 6m+5

Adding that to the 14m, we end up with

rArr14m+6m+5

The simplified form will be

20m+5
