\n" ); document.write( "find all other zeros give 2i is one zero.
\n" ); document.write( "f(x) = x^5 - 3x^4 + 5x^3 - 15x^2 + 4x - 12
\n" ); document.write( "

One zero is 2i, so the other, its conjugate is: - 2i
\n" );
document.write( "This gives us: (x - 2i)(x + 2i), or 
\n" );
document.write( "Dividing  by  results in:
\n" );
document.write( ", which can be factored into: 
\n" );
document.write( "
\n" );
document.write( "
\n" );
document.write( ".
\n" );
document.write( "This leads to zeroes of: - i, i, and 3.
\n" );
document.write( "Thus the zeroes of  are:  \n" );
document.write( "

\n" );
