Question 75960
<pre>

      2               3 
___________   -   ________
  5w + 10          2w – 4


Since the denominators are not the same, we will find LCD (least common denominator)= (5w + 10)(2w - 4)


      2       (5w + 10)(2w - 4)         3        (5w + 10)(2w - 4)
___________ * _________________  -   ________ * ___________________
  5w + 10     (5w + 10)(2w - 4)       2w – 4     (5w + 10)(2w - 4)




     2 ( 2w - 4)             3(5w + 10)
___________________  -  ___________________
 (5w + 10)(2w - 4)       (5w + 10)(2w - 4)




     4w - 8                  15w + 30
___________________  -  ___________________
 (5w + 10)(2w - 4)       (5w + 10)(2w - 4)




     4w - 8  - (15w + 30)
    ______________________  
     (5w + 10)(2w - 4)    




     4w - 8  - 15w - 30)
    ______________________  
     (5w + 10)(2w - 4)  




        -11w - 38
    _______________________
      (5w + 10)(2w - 4)
