If a polynomial has a zero then the polynomial has a factor of the form:
\n" ); document.write( "(x - z)
\n" ); document.write( "where \"z\" is the zero.

\n" ); document.write( "Your polynomial, with zeros of 2, 2i and -2i, will have factor of:
\n" ); document.write( "(x - 2)(x - 2i)(x - (-2i))
\n" ); document.write( "The third factor simplifies to:
\n" ); document.write( "(x - 2)(x - 2i)(x + 2i)

\n" ); document.write( "All you have to do now is multiply. I suggest that you start by multiplying the last two factors first. (Hint: the i's will disappear!)
\n" ); document.write( "

\n" );
