Uncut square, \"x%5E2\" area. Side length is x.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Remaining rectangle, \"x%28x-3%29\" area. This was given a value \"10%2Acm%5E2\".
\n" ); document.write( "\"x%5E2-3x=10\"
\n" ); document.write( "\"x%5E2-3x-10=0\"
\n" ); document.write( "\"%28x%2B2%29%28x-5%29=0\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The meaningful solution is \"highlight%28x=5%29\".
