let length be x inches
\n" ); document.write( "width will be x-9 inches
\n" ); document.write( "area = 322 sq. in
\n" ); document.write( "Area = L*W
\n" ); document.write( "x(x-9)=322
\n" ); document.write( " $\"x%5E2-9x=322\"$
\n" ); document.write( "add-322 to both sides
\n" ); document.write( " $\"x%5E2-9x-322=322-322\"$
\n" ); document.write( " $\"x%5E2-9x-322=0\"$
\n" ); document.write( " $\"x%5E2-23x%2B14x-322=0\"$
\n" ); document.write( " $\"x%28x-23%29%2B14%28x-23%29=0\"$
\n" ); document.write( "(x-23)(x+!4)=0
\n" ); document.write( "x=23 OR -14
\n" ); document.write( "ignore the negative value
\n" ); document.write( "length = 14 inches
\n" ); document.write( "width = 14-9=5 inches \n" ); document.write( "

\n" );
