**the directions are to simplify completely.....**

I am not too sure how to write these so you can see what the problem looks like exactally....... but I'll try to explain it......

1) 1+ 2/d -3

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

-2d/ d-3 - d

This problem reads 1 + 2 over (d -3), all over -2d over (d - 3). the -d is written after the fraction. I hope this kind of makes sense...... in my book it say the answer is -1/d but I keep getting something completely different....

to begin, on the top I multiply the 1/1 by (d - 3) to get the lcd so I can add them and then I can cancel the d - 3 from the top and the bottom and I am left with 2

for the bottom part..... I multiplied (-2d/d - 3) by d and I multiplied the (- d) by (d - 3) to get the lcd d(d - 3)

I got -d (2d) / d(d - 3) minus d (d - 3) so I end up with - d (2d) - d (d - 3)/ d (d - 3) and cancel the d (d - 3)

I get for the final simplification, - 2/ d (2d) where nothing can be cancelled or combined as they are not like terms.... but the answer in my book is - 1/d can someone please highlight what I did wrong here? I really struggle with these types of problems.......
