Find a polynomial function of degree 3 with zeros 1/2, 1-i; where P(4) = 140
\n" ); document.write( "

\r\n" );
document.write( "Since the polynomial is to have real coefficients, since 1-i is a zero,\r\n" );
document.write( "its conjugate 1+i is also a zero\r\n" );
document.write( "\r\n" );
document.write( "So the polynomial is\r\n" );
