$\"%283x%2B5%29%28x-1%29=x%5E2%2B9x-1\"$
\n" ); document.write( " $\"3x%5E2+-3x+%2B+5x+-+5+=+x%5E2%2B9x-1\"$
\n" ); document.write( " $\"3x%5E2+%2B2x+-+5+=+x%5E2%2B9x-1\"$
\n" ); document.write( " $\"2x%5E2+-7x+-4+=+0\"$
\n" ); document.write( " $\"%282x%2B1%29%28x-4%29+=+0\"$
\n" ); document.write( "so either 2x+1=0 or x-4=0
\n" ); document.write( "and x is either -1/2, or 4 \n" ); document.write( "

\n" );
