how do I find the roots of this equation using only pencil paper and some sort of advanced algorithm: (2+i)*x^9-2*x^5+i*x^3+6*i*x-(8-3*i)=0?

can anyone please direct me to or give me the algorithm or algorithms.

In general, you

**don't**. It can be shown that there exist equations of degree higher than four whose solutions simply cannot be written in terms of algebraic operations (adding, multiplying, roots).
