\n" ); document.write( "x = length
\n" ); document.write( "y = width
\n" ); document.write( "x = y - 5
\n" ); document.write( "xy = 36
\n" ); document.write( "---
\n" ); document.write( "xy = 36
\n" ); document.write( "(y - 5)y = 36
\n" ); document.write( "yy - 5y - 36 = 0
\n" ); document.write( "---
\n" ); document.write( "the above quadratic equation is in standard form, with a=1, b=-5, and c=-36
\n" ); document.write( "---
\n" ); document.write( "to solve the quadratic equation, by using the quadratic formula, copy and paste this:
\n" ); document.write( "1 -5 -36
\n" ); document.write( "into this solver: https://sooeet.com/math/quadratic-equation-solver.php
\n" ); document.write( "---
\n" ); document.write( "this quadratic has two real roots (the x-intercepts), which are:
\n" ); document.write( "y = 9
\n" ); document.write( "y = -4
\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( "x = length = 4 in
\n" ); document.write( "y = width = 9 in
