The denominators of the fractions are the same, so we can subtract the numerators and place that over the LCD

4%2F%28x%2B2%29+-+3%2F%28x%2B2%29+=+%284-3%29%2F%28x%2B2%29

4%2F%28x%2B2%29+-+3%2F%28x%2B2%29+=+1%2F%28x%2B2%29


------------------------------------------

So 4%2F%28x%2B2%29+-+3%2F%28x%2B2%29 simplifies to 1%2F%28x%2B2%29

4/(x+2) - 3/(x+2)They have a common denominator, so the denominator stays. Then:
4-3 = 1 so your answer is:
1/(x+2)
