Thread: Reduce fraction in LaTex

So I know how to reduce simple fractions is Latex with

\frac{3x}{3y}=\frac{\not{3}x}{\not{3}y}



But if I try with a binomial it only crosses out the parenthesis.



Any ideas would be awesome.

Hello, TheEmptySet!

I see that \cancel{ } doesn't work at this site.


The command \rlap{////} superimposes //// over the next expression.


\rlap{/////}x+y . . .


\frac{3(\rlap{////}a+b)}{\rlap{////}a+b} = 3 . . .


\rlap{////}\backslash\backslash\backslash\backslash . . .


\rlap{ooo}|||||| . . .


Some symbols can't be used. .You need to experiment.
