I'm stumped on this problem, I need to know how this answer was arrived at but my text book doesn't show this.
The text book says the answer is this:
I think the problem is that I lack the insight to find the correct LCD, but I tried this, and it's obviously wrong. $$y(x+y)$$
How can the correct LCD for this be obtained and how is this problem solved assuming the text book's answer is even correct?
The textbook instructed to simplify this, not divide it. But it is definitely a division problem as
@Azmoti emphasized. Context, and the way in which the problem was rendered is the real problem here.
