<PRE><B>Question 687737</B>
I need help with finding all the zeroes of an equation.
x^4-6x^2-7x-6=0 

-----
I graphed it and found Real Number zeroes at x = 3 and at -2
-----
Use synthetic division to find the quadratic quotient:
----
3)....1...0....-6....-7....-6..
......1...3.....3....+2...|..0

-2)...1...1.....1...|..0

----
Quadratic quotient: x^2 + x + 1
----
Use the Quadratic formula to find the zeroes of that quadratic.
