\n" ); document.write( "x + y = 13
\n" ); document.write( "xx + yy = 229
\n" ); document.write( "---
\n" ); document.write( "y = 13 - x
\n" ); document.write( "xx + (13 - x)(13 - x) = 229
\n" ); document.write( "---
\n" ); document.write( "xx + 169 - 26x + xx = 229
\n" ); document.write( "2xx - 26x - 60 = 0
\n" ); document.write( "---
\n" ); document.write( "the above quadratic equation is in standard form, with a=2, b=-26, and c=-60
\n" ); document.write( "---
\n" ); document.write( "to solve the quadratic equation, by using the quadratic formula, copy and paste this:
\n" ); document.write( "2 -26 -60

\n" ); document.write( "---
\n" ); document.write( "this quadratic has two real roots (the x-intercepts), which are:
\n" ); document.write( "x = 15
\n" ); document.write( "x = -2
\n" ); document.write( "---
\n" ); document.write( "answer:
\n" ); document.write( "the two numbers are: 15 and -2
