show

and are equal when x = 2 and x = -1.

True or False?/ They are equivalent expressions on (-infinity,infinity)

I'm lost. How do you do this?

Thank you!

how did you do it from that to this:

I multiplied by which simplifies to 1. You can do that, because 1 X anything = that same anything. I did this so the two fractions at the bottom would have the same denominator, allowing them to be added. If you continue to look at what I did, I used that method about five times to add the fractions to 1.
