a = Lw = 27
\n" ); document.write( "L = 2w - 3
\n" ); document.write( "---
\n" ); document.write( "Lw = 27
\n" ); document.write( "(2w - 3)w = 27
\n" ); document.write( "2w^2 - 3w - 27 = 0
\n" ); document.write( "---
\n" ); document.write( "the above quadratic equation is in standard form, with a=2, b=-3, and c=-27
\n" ); document.write( "---
\n" ); document.write( "to solve the quadratic equation, plug this:
\n" ); document.write( "2 -3 -27
\n" ); document.write( "into this: https://sooeet.com/math/quadratic-equation-solver.php
\n" ); document.write( "---
\n" ); document.write( "the roots of the quadratic are:
\n" ); document.write( "4.5
\n" ); document.write( "-3
\n" ); document.write( "---
\n" ); document.write( "the negative root doesn't make sense for a length, so use the positive root
\n" ); document.write( "---
\n" ); document.write( "w = 4.5
\n" ); document.write( "L = 6
