Find the real-number solutions of the equation.
x^3+2x^2-25x-50=0
----------
I graphed it to find x=-5 is a root.
-------
Using synthetic division find the other roots:
-5)....1....2....-25...-50
........1....-3....-10..|..0
-2).....1-----5....|..0
5)......1....|0
=========================
x = -5 or -2 or 5
