\n" ); document.write( "Lw = 560
\n" ); document.write( "L = 2w + 3
\n" ); document.write( "---
\n" ); document.write( "Lw = 560
\n" ); document.write( "(2w + 3)w = 560
\n" ); document.write( "2ww + 3w - 560 = 0
\n" ); document.write( "---
\n" ); document.write( "the above quadratic equation is in standard form, with a=2, b=3, and c=-560
\n" ); document.write( "---
\n" ); document.write( "to solve the quadratic equation, by using the quadratic formula, copy and paste this:
\n" ); document.write( "2 3 -560

\n" ); document.write( "this quadratic has two real roots (the x-intercepts), which are:
\n" ); document.write( "w = 16
\n" ); document.write( "w = -17.5
\n" ); document.write( "---
\n" ); document.write( "negative width doesn't make sense for this problem, so use the positive root
\n" ); document.write( "---
\n" ); document.write( "answer:
\n" ); document.write( "w = 16 in
