How to solve for polynomial equations
WebThe easiest thing is just try to guest a root of the polynomial first. In this case, for p(z) = z3 − 3z2 + 6z − 4, we have that p(1) = 0. Therefore, you can factorize it further and get z3 − 3z2 + 6z − 4 = (z − 1)(z2 − 2z + 4) = (z − 1)((z − 1)2 + 3). Their roots are just z1 = 1, z2 = 1 + i√3, z3 = 1 − i√3.
