Lw = 54
\n" ); document.write( "L = 2w + 3
\n" ); document.write( "---
\n" ); document.write( "(2w + 3)w = 54
\n" ); document.write( "2ww + 3w - 54 = 0
\n" ); document.write( "---
\n" ); document.write( "the above quadratic equation is in standard form, with a=2, b=3 and c=-54
\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 -54

\n" ); document.write( "---
\n" ); document.write( "the quadratic has two real roots at:
\n" ); document.write( "---
\n" ); document.write( "w = 4.5
\n" ); document.write( "w = -6
\n" ); document.write( "---
\n" ); document.write( "the negative root doesn't fit the problem statement, so use the positive root:
\n" ); document.write( "---
\n" ); document.write( "w = 4.5
\n" ); document.write( "L = 2w + 3
\n" ); document.write( "L = 2*4.5 + 3
\n" ); document.write( "L = 12
\n" ); document.write( "---
\n" ); document.write( "answer:
\n" ); document.write( "w = 4.5 yd
\n" ); document.write( "L = 12 yd
