xy = 192
\n" ); document.write( "x + y = -28
\n" ); document.write( "y = -28 - x
\n" ); document.write( "---
\n" ); document.write( "xy = 192
\n" ); document.write( "x(-28 - x) = 192
\n" ); document.write( "-28x - xx - 192 = 0
\n" ); document.write( "-xx - 28x - 192 = 0
\n" ); document.write( "---
\n" ); document.write( "the above quadratic equation is in standard form, with a=-1, b=-28 and c=-192
\n" ); document.write( "---
\n" ); document.write( "to solve the quadratic equation, by using the quadratic formula, copy and paste this:
\n" ); document.write( "-1 -28 -192

\n" ); document.write( "---
\n" ); document.write( "the quadratic has two real roots at:
\n" ); document.write( "---
\n" ); document.write( "x = -16
\n" ); document.write( "x = -12
\n" ); document.write( "---
\n" ); document.write( "y = -28 - x
\n" ); document.write( "y = -28 - -16
\n" ); document.write( "y = -28 + 16
\n" ); document.write( "y = -12
\n" ); document.write( "---
\n" ); document.write( "answer:
\n" ); document.write( "x = -16
\n" ); document.write( "y = -12
