\n" ); document.write( "x - y = -2
\n" ); document.write( "x = y - 2
\n" ); document.write( "xy = 399
\n" ); document.write( "---
\n" ); document.write( "xy = 399
\n" ); document.write( "(y - 2)y = 399
\n" ); document.write( "yy - 2y - 399 = 0
\n" ); document.write( "---
\n" ); document.write( "the above quadratic equation is in standard form, with a=1, b=-2, and c=-399
\n" ); document.write( "---
\n" ); document.write( "to solve the quadratic equation, by using the quadratic formula, copy and paste this:
\n" ); document.write( "1 -2 -399

\n" ); document.write( "the two real roots (i.e. the two x-intercepts), of the quadratic are:
\n" ); document.write( "y = 21
\n" ); document.write( "y = -19
\n" ); document.write( "---
\n" ); document.write( "positive root doesn't satisfy the problem statement, so use the negative root:
