Being that the numbers are4 not the most "user friendly", I'd be apt to graph on a graphing calculator and find where the graph crosses the x-axis (roots). The Ti calculators have function to find roots of equations. Only 1 reat root of x=-6.528568. The ohter roots will be imaginary.
Algebraically this would not be fun! Need to use synthetic or long division.
