.
.
To combine these terms just combine the multipliers of
and multiply the
result of this combination by
to give you
.
.
Another way of looking at the problem is that since every one of the terms has
as a factor it can be factored out. The result is:
.
.
Then combine the terms inside the parentheses. 10 - 7 + 5 = +8. So you can replace the three
terms in the parentheses by +8 and the problem becomes:
.
.
and by convention we normally write this in the reverse order:
.
.
Therefore, the third answer in your list of answers is the correct one ...

Hope this helps you to understand the problem.
