59. Use polynomial long division to find (x^2 + 4) / (x - 2i). i is an Imaginary number.
We have to remember to account for missing powers in the dividend....so....x^2 + 4 is actually
x^2 + 0x + 4......so we have
x + 2i
x - 2i [ x^2 + 0 x + 4 ]
x^2 -2ix
___________________________________
2ix + 4
2ix - 4i^2
________________
0
In the last subtraction, we actually have 4 - (-4i^2) = 4 + 4i^2 = 4 + 4(-1) = 0
