$\"%28x%2B2%29%283x-4%29=448\"$
\n" ); document.write( " $\"3x%5E2-4x%2B6x-8=448\"$
\n" ); document.write( " $\"3x%5E2%2B2x-8=448\"$
\n" ); document.write( " $\"3x%5E2%2B2x-456=0\"$
\n" ); document.write( " $\"%28x-12%29%283x%2B38%29=0\"$
\n" ); document.write( "Only the positive solution makes sense here.
\n" ); document.write( " $\"x-12=0\"$
\n" ); document.write( " $\"x=12\"$
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "So then,
\n" ); document.write( " $\"x%2B2=12%2B2=14\"$ $\"ft\"$
\n" ); document.write( " $\"3x-4=3%2812%29-4=36-4=32\"$ $\"ft\"$ \n" ); document.write( "

\n" );
