xx = 2x + 168
\n" ); document.write( "xx - 2x - 168 = 0
\n" ); document.write( "---
\n" ); document.write( "the above quadratic equation is in standard form, with a=1, b=-2 and c=-168
\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 -168

\n" ); document.write( "the quadratic has two real roots at:
\n" ); document.write( "---
\n" ); document.write( "x = 14
\n" ); document.write( "x = -12
\n" ); document.write( "---
\n" ); document.write( "answer:
\n" ); document.write( "14 or -12
