This is how I interpreted your problem and I hope that is correct.
.
In the numerator let's put everything over the common denominator of (x+2). We can do that
by replacing the 1 with %28x%2B2%29%2F%28x%2B2%29 and this will make the numerator:
.
%28%28x%2B2%29%2F%28x%2B2%29%29-%282%2F%28x%2B2%29%29%29
.
and when you combine this numerator over its common denominator the result is:
.
%28x%2B2+-2%29%2F%28x%2B2%29
.
and this further simplifies to:
.
%28x%29%2F%28x%2B2%29
.
Next we'll do the same thing to the denominator.
In the denominator let's put everything over the common denominator of (x-2). We can do that
by replacing the 1 with %28x-2%29%2F%28x-2%29 and this will make the denominator become:
.
%28%28x-2%29%2F%28x-2%29%29%2B%282%2F%28x-2%29%29%29
.
and when you combine this over its common denominator the result is:
.
%28x-2+%2B2%29%2F%28x-2%29
.
and this further simplifies to:
.
%28x%29%2F%28x-2%29
.
Now, putting the numerator and denominator back together in their new forms we get:
.
%28%28x%29%2F%28x%2B2%29%29%2F%28%28x%29%2F%28x-2%29%29%29
.
The rule for dividing by a fraction (the denominator) is to invert it and multiply it
times the number being divided. We can apply that rule here and get:
.
%28%28x%29%2F%28x%2B2%29%29%2A%28%28x-2%29%2Fx%29
.
which when multiplied becomes
.
%28x%2A%28x-2%29%29%2F%28x%2A%28x%2B2%29%29
.
canceling the x in the denominator with the x in the numerator finally gets us to the answer:
.
%28x-2%29%2F%28x%2B2%29
.
Hope I interpreted your problem correctly and this is the work you were looking for.
