Two questions: 1) Is this the expression? \[\frac{3}{x+5}-\frac{3x}{3+15}+\frac{1}{2x+10}\]2) Wht do they want you to do here? (I'm guessing they want you to simplify it into a single fraction...)
find the lcd
then simplify the answer
look 3x/3x= zero so just get rid of that then 5 -15= -10 -10 +10 = 0 so ur left with 3/x + 1/2x which is just 4/x
3x/3x doesn't equal 0 but 1....O.o
