\n" ); document.write( "Use the quadratic formula:
\n" ); document.write( "x = [2 +- sqrt(4 -4*-13)]/2
\n" ); document.write( "----
\n" ); document.write( "x = [2 +- sqrt(56)]/2
\n" ); document.write( "----
\n" ); document.write( "x = [2 +- 2sqrt(14)]/2
\n" ); document.write( "---
\n" ); document.write( "x = [1 +- sqrt(14)]
