Strikeout in fraction equation

Question

I am having trouble getting the strikeout to work in this equation. I'd appreciate your help.

Thanks. I have tried variations of the \sout [\frac{(x-2)\sout{(x+1)}}{x+1}=x-2] — tina, Jan 18 '22 at 19:47

Welcome to TeX:SE!

For such purposes is package cancel:

\documentclass{article}
\usepackage{cancel}
\begin{document}
[
\frac{(x-2)\cancel{(x+1)}}{\cancel{x+1}} = x-2
]
\end{document}

@Mico, you are right. I forgot on divisor. Corrected now. – Zarko Jan 18 '22 at 08:39
The full code provided did not work however, shortened to this works. [\frac{(x-2)\cancel{(x+1)}}{\cancel{x+1}} = x-2]. Thanks – tina Jan 18 '22 at 19:54
@tina, I do not understand your comment. What does not work? What error you receive? My solution (as it is) definitely works, so I wonder what you change in your test. – Zarko Jan 18 '22 at 21:57
I cut and pasted your code (changed nothing) and put it into my document. When I save, if it doesn't work, I see the code; if it does work I see the formatted equation. When I removed the first three lines and the last line of your code - it did work I saw the equation you have screen clipped above. For some reason the system I use doesn't need? like? the begin/end code. I have experienced this issue in the past. Thank you for helping you solved it anyway. :-) – tina Jan 19 '22 at 19:24
