SOLUTION: Im not sure if this is the correct area but I need some help with this problem. I have a problem understanding math, especially when there's to many part. So here it is. ADD 2x/x

You must get the LCD.  Since none will factor and they are all
different, we find the LCD by multiplying them together:

 or since it is customary to put the
shortest factor first,



Put parentheses around all three terms:




Next we multiply each fraction top and bottom by all the
factors of the LCD which its denominator needs to be multiplied 
by in order to become equal to the LCD:

The fraction  needs to be multiplied top and
bottom by both  and by  

The fraction  needs to be multiplied top and bottom 
both by  and by  

The fraction  needs to be multiplied both by 
and by 



Indicate the multiplication of the numerators and denominators:



Now we multiply the numerators out, but NOT the denominators.
Notice that the denominators are all equal to the LCD, 




Finish multiplying out the numerators:



Now we combine the three numerators all over the LCD:



Remove the parentheses in the top:



Combine all the like terms in the top:
