Use the quadratic formula,
\n" ); document.write( " $\"x%5E2-4x%2B6=0\"$
\n" ); document.write( " $\"a=1\"$
\n" ); document.write( " $\"b=-4\"$
\n" ); document.write( " $\"c=6\"$
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( " $\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"$
\n" ); document.write( " $\"x+=+%284+%2B-+sqrt%28+%28-4%29%5E2-4%2A1%2A6+%29%29%2F%282%2A1%29+\"$
\n" ); document.write( " $\"x+=+%284+%2B-+sqrt%28+16-24%29%29%2F2+\"$
\n" ); document.write( " $\"x+=+%284+%2B-+sqrt%28+-8%29%29%2F2+\"$
\n" ); document.write( " $\"x+=+%284+%2B-+2sqrt%28+-2%29%29%2F2+\"$
\n" ); document.write( " $\"highlight%28x+=+2+%2B-+sqrt%28+2%29i+%29\"$ where $\"i=sqrt%28-1%29\"$
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "Now follow the same procedure for the second equation.
\n" ); document.write( " \n" ); document.write( "

\n" );
