Lw = 99 sq.yd
\n" ); document.write( "L = 2w + 7
\n" ); document.write( "---
\n" ); document.write( "Lw = 99
\n" ); document.write( "(2w + 7)w = 99
\n" ); document.write( "2ww + 7w = 99
\n" ); document.write( "2ww + 7w - 99 = 0
\n" ); document.write( "---
\n" ); document.write( "the above quadratic equation is in standard form, with a=2, b=7, and c=-99
\n" ); document.write( "---
\n" ); document.write( "to solve the quadratic equation, plug this:
\n" ); document.write( "2 7 -99
\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( "-9
\n" ); document.write( "5.5
\n" ); document.write( "---
\n" ); document.write( "the negative root doesn't make sense as a length, so use the positive root:
\n" ); document.write( "---
\n" ); document.write( "w = 5.5
\n" ); document.write( "L = 18
