<PRE><B>Question 931827</B>
Solve the following equation by identifying all of its roots including any imaginary numbers. In your final answer, include the necessary steps and calculations. Hint: Use your knowledge of factoring polynomials.
 (x^ 2 + 1)(x^ 3 + 2x)(x ^2 + 4x - 16i - 4xi) = 0 

-------------
(x-i)(x+i)(x)*(x+sqrt(2)i)(x-sqrt(2)i)(x+4)(x-4i)) = 0
-----
x = i or -i or -sqrt(2)i or +sqrt(2)i or -4 or 4i
