Question 954858
How to simplify (4x/x+3)-(4x/x+6)


This can be solved by taking the common denominator and finally simplifying it 
     We can first take out 4x common from the both the terms


              4x( 1/x+3 - 1/x+6)

Now the common denominator is (x+3).(x+6)

               4x [(x+6) - (x+3)]/[(x+3).(x+6)]

               4x [ x + 6 - x - 3]/[(x+3).(x+6)]

               4x [ 3/(x+3).(x+6)]
