Solve: 0 = x^3 - x^2 - 11x - 10
--------------
I graphed to find solutions:
------------------
Using synthetic division to find the remaining zeroes:
-2)....1....-1....-11....-10
........1.....-3.....-5...|..0
Quotient = x^2-3x-5
x = [3 +- sqrt(9 - 4*-5)]/2
x = [3 +- sqrt(29)]/2
x = [3+sqrt(29)]/2 or x = [3-sqrt(29)]/2
x = 4.1925824.. or x = -1.192582...
