\n" ); document.write( "x = length
\n" ); document.write( "y = width
\n" ); document.write( "---
\n" ); document.write( "x = 3y
\n" ); document.write( "(x + 2)(y + 2) = 32
\n" ); document.write( "---
\n" ); document.write( "(x + 2)(y + 2) = 32
\n" ); document.write( "(3y + 2)(y + 2) = 32
\n" ); document.write( "3yy + 6y + 2y + 4 = 32
\n" ); document.write( "3yy + 8y - 28 = 0
\n" ); document.write( "---
\n" ); document.write( "the above quadratic equation is in standard form, with a=3, b=8, and c=-28
\n" ); document.write( "---
\n" ); document.write( "to solve the quadratic equation, by using the quadratic formula, copy and paste this:
\n" ); document.write( "3 8 -28
\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 = 2
\n" ); document.write( "y = -4.66666667
\n" ); document.write( "---
\n" ); document.write( "the negative root does not fit the problem statement, so use the positive root
\n" ); document.write( "---
\n" ); document.write( "answer:
\n" ); document.write( "x = length = 6 cm
\n" ); document.write( "y = width = 2 cm
