Use the formula:
\n" ); document.write( "Area of a rectangle = length*width\r
\n" ); document.write( "\n" ); document.write( "So
\n" ); document.write( "A = \"%282x-1%29%28x%2B2%29\"\r
\n" ); document.write( "\n" ); document.write( "A can also be written in expanded form
\n" ); document.write( "A =\"2x%5E2-x%2B4x-2\"
\n" ); document.write( "=\"2x%5E2%2B3x-2\"\r
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "
\n" );
