andrew is wrong because he used a postive instead of a negative
+128468 Here you go....we need this :
[ x - 3 ] [ x - (2 + 2i) ] [ x - (2 - 2i) ] = 0
[x - 3 ] [ x^2 - (2 + 2i)x - (2 - 2i)x + (2 + 2i)(2-2i) ] = 0
[ x - 3 ] [ x^2 -2x - 2ix - 2x + 2ix + 4 - 4i^2 ] = 0
[ x - 3 ] [ x^2 - 4x + 4 + 4 ] = 0
[x - 3 ] [ x^2 - 4x + 8 ] = 0
[ x^3 - 4x^2 + 8x - 3x^2 + 12x - 24 ] = 0
x^3 - 7x^2 + 20x - 24 = 0
