\n" ); document.write( "L+w=4
\n" ); document.write( "L=4-w
\n" ); document.write( ".

\n" ); document.write( "Lw=3.84
\n" ); document.write( "w(4-w)=3.84
\n" ); document.write( "4w-w^2=3.84
\n" ); document.write( "w^2-4w=-3.84 multiply each side by -1.
\n" ); document.write( "w^2-4w+4=4-3.84 completing the square.
\n" ); document.write( "(w-2)^2=.16
