got a feeling that this is either a question misread mistyped or is not serious..
here's the numerical solution
-30x(x+.9473257766+.5908091171*I)*(x+.9473257766-.5908091171*I)*
(x+.6058164360e-1+.7558248859*I)*(x+.6058164360e-1-.7558248859*I)*
(x-.4353580824+.9088078674*I)*(x-.4353580824-.9088078674*I)*(x-1.145098676)
