(z-3)^2=-18
\n" ); document.write( "z^2-6z+9+18=0
\n" ); document.write( "z^2-6z+27=0
\n" ); document.write( " $\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"$
\n" ); document.write( "z=(6+-sqrt[6^2-4*1*27])/2*1
\n" ); document.write( "z=(6+-sqrt[36-108])/2
\n" ); document.write( "z=(6+-sqrt-72)/2
\n" ); document.write( "z=(6+-8.485i)/2
\n" ); document.write( "z=6/2+-8.485i/2
