\n" ); document.write( "---
\n" ); document.write( "Lw = 16
\n" ); document.write( "(3w + 2)w = 16
\n" ); document.write( "3ww + 2w - 16 = 0

\n" ); document.write( "the above quadratic equation is in standard form, with a=3, b=2, and c=-16
\n" ); document.write( "---
\n" ); document.write( "to solve the quadratic equation, by using the quadratic formula, copy and paste this:

\n" ); document.write( "the two real roots (i.e. the two x-intercepts), of the quadratic are:
\n" ); document.write( "w = 2
\n" ); document.write( "w = -2.66666667
\n" ); document.write( "---
\n" ); document.write( "negative width doesn't make sense so use the positive root:
\n" ); document.write( "---
\n" ); document.write( "answer:
\n" ); document.write( "w = 2 yards
\n" ); document.write( "L = 8 yards
