How do you change it so that they are the same?
For example, this problem:
Almost the same. Slight adjuistment:
Multiply the right side by (X+h) / (X+h) and the left side by X / X. Then both sides will have the same denominator, X * (X+h), and you can just subtract the right numerator from the left.
(Sorry about the typo - in my original note, I said (X+h) / (X+2) when I meant (X+h) / (X+h).
Hope this helps.
