# My text is cropped when exporting using lyx

When i'm exporting my lyx to pdf (or even when running the latex code) my text is cropped :

Tried playing with document setting but could not find any thing there. any idea? Here the code from latex :

%% LyX 2.2.3 created this file.  For more info, see http://www.lyx.org/.
%% Do not edit unless you really know what you are doing.
\documentclass[english]{article}
\usepackage[T1]{fontenc}
\usepackage[latin9]{luainputenc}
\usepackage{amsmath}
\usepackage{babel}
\begin{document}
Here is a test , im' writing things and adding things like : $U=\left[\begin{array}{cccc} 2 & 5 & -4 & -10\\ 1 & 1 & 1 & 1\\ 1 & 0 & 3 & 5\\ 0 & 2 & -4 & -8 \end{array}\right]\tbinom{R_{1}\rightarrow R_{1}-2R_{3}}{R_{2}\rightarrow R_{2}-R_{3}}\left[\begin{array}{cccc} 0 & 5 & -10 & -20\\ 0 & 1 & -2 & -4\\ 1 & 0 & 3 & 5\\ 0 & 2 & -4 & -8 \end{array}\right]\tbinom{R_{1}\rightarrow R_{1}-5R_{2}}{R_{4}\rightarrow R_{4}-2R_{2}}\left[\begin{array}{cccc} 0 & 0 & 0 & 0\\ 0 & 1 & -2 & -4\\ 1 & 0 & 3 & 5\\ 0 & 0 & 0 & 0 \end{array}\right]\tbinom{R_{1}\Leftrightarrow R_{3}}{R_{2}\Leftrightarrow R_{4}}\left[\begin{array}{cccc} 1 & 0 & 3 & 5\\ 0 & 1 & -2 & -4\\ 0 & 0 & 0 & 0\\ 0 & 0 & 0 & 0 \end{array}\right]$and another $U=\left[\begin{array}{cccc} 2 & 5 & -4 & -10\\ 1 & 1 & 1 & 1\\ 1 & 0 & 3 & 5\\ 0 & 2 & -4 & -8 \end{array}\right]\tbinom{R_{1}\rightarrow R_{1}-2R_{3}}{R_{2}\rightarrow R_{2}-R_{3}}\left[\begin{array}{cccc} 0 & 5 & -10 & -20\\ 0 & 1 & -2 & -4\\ 1 & 0 & 3 & 5\\ 0 & 2 & -4 & -8 \end{array}\right]\tbinom{R_{1}\rightarrow R_{1}-5R_{2}}{R_{4}\rightarrow R_{4}-2R_{2}}\left[\begin{array}{cccc} 0 & 0 & 0 & 0\\ 0 & 1 & -2 & -4\\ 1 & 0 & 3 & 5\\ 0 & 0 & 0 & 0 \end{array}\right]\tbinom{R_{1}\Leftrightarrow R_{3}}{R_{2}\Leftrightarrow R_{4}}\left[\begin{array}{cccc} 1 & 0 & 3 & 5\\ 0 & 1 & -2 & -4\\ 0 & 0 & 0 & 0\\ 0 & 0 & 0 & 0 \end{array}\right]$

This is not a LyX problem, nor a LaTeX one. Your formulas are simply too long to be kept in line. You should display them, for a start (Menu Insert/Math/Display formula in LyX). If they are still too long, there is still the possibility of breaking them in several lines (Insert/Math/Align-gather-multline…)
