Question 716422
Find all Zero's X^3+7X^2+7X-15=F(x)
-------
Since the coefficients add up to 0 x=1 is a root.
Use synthetic division to find the remaining 2 roots:
-------------
1)....1....7....7....-15
......1....8....15..|..0
-----

Solve the quotient for roots:
x^2 + 8x + 15 = 0
(x+3)(x+5) = 0
----
Roots:  x = -3 ; x = -5 ; x = 1
