Substitute, let $\"u=%28x-1%29%2Fx\"$
\n" ); document.write( "Then,
\n" ); document.write( " $\"u%5E2-u-2=0\"$
\n" ); document.write( " $\"%28u-2%29%28u%2B1%29=0\"$
\n" ); document.write( "Two solutions:
\n" ); document.write( " $\"u-2=0\"$
\n" ); document.write( " $\"u=2\"$
\n" ); document.write( " $\"%28x-1%29%2Fx=2\"$
\n" ); document.write( " $\"x-1=2x\"$
\n" ); document.write( " $\"highlight%28x=-1%29\"$
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( " $\"u%2B1=0\"$
\n" ); document.write( " $\"u=-1\"$
\n" ); document.write( " $\"%28x-1%29%2Fx=-1\"$
\n" ); document.write( " $\"x-1=-x\"$
\n" ); document.write( " $\"2x=1\"$
\n" ); document.write( " $\"highlight%28x=1%2F2%29\"$ \n" ); document.write( "

\n" );
