    Unlike Fractions with + in the Denominator

    How do you change it so that they are the same?

    For example, this problem:
    Simplify.
    \dfrac{2}{x+h} = \dfrac{2}{x}

    Unlike Fractions with + in the Denominator

    Multiply the left side by (X+h) / (X+2) and the right side by X / X. Then both sides will have the same denominator, X * (X+h), and you can just add the numerators together.

    Whoops, sorry.
    I meant:
    \dfrac{2}{x+h} - \dfrac{2}{x}

    or would you still do it the same way?

    Unlike Fractions with + in the Denominator

    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.
