<PRE><B>Question 199774</B>
Find all real zeros of the polynomial. Use the quadratic formula if necessary 
P(x) = x^4 + x^3 - 5x^2 - 4x + 4 
--------------
By graphing, x = 2 and x = -2
-------------------
Divide by (x^2 - 4) to get:
x^2 + x - 1 = 0
*[invoke solve_quadratic_equation 1,1,-1]
---------------
I got the +2 and -2 by graphing using the software from 
www.padowan.dk.com/graph/
FREE software, btw
