Write a polynomial function of least degree with integral coefficients whose zeros include 4 and 2i.
\n" ); document.write( ":
\n" ); document.write( "We have:
\n" ); document.write( "x = 4, therefore one of the factors is (x-4)
\n" ); document.write( "Also
\n" ); document.write( "x = 2i
\n" ); document.write( "same as:
\n" ); document.write( "x = Sqrt(-4)
\n" ); document.write( "Square both sides:
\n" ); document.write( "x^2 = -4
\n" ); document.write( ":
\n" ); document.write( "x^2 + 4 = 0
\n" ); document.write( ":
\n" ); document.write( "Our equation has factors: (x-4)(x^2 + 4)
\n" ); document.write( "FOIL this:
\n" ); document.write( "x^3 + 4x - 4x^2 - 16
\n" ); document.write( "or
\n" ); document.write( "x^3 - 4x^2 + 4x - 16, the normal order
