L = w + 7
\n" ); document.write( "Lw = 98
\n" ); document.write( "---
\n" ); document.write( "Lw = 98
\n" ); document.write( "(w + 7)w = 98
\n" ); document.write( "ww + 7w = 98
\n" ); document.write( "ww + 7w - 98 = 0
\n" ); document.write( "---
\n" ); document.write( "the above quadratic equation is in standard form, with a=1, b=7, and c=-98
\n" ); document.write( "---
\n" ); document.write( "to solve the quadratic equation, plug this:
\n" ); document.write( "1 7 -98
\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( "7
\n" ); document.write( "-14
\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 = 7 feet
\n" ); document.write( "L = 14 feet
