Question

what are the zeros of f(x) = x3 + 3x2 - x - 3

Answer 1

use the "rational root test" to find one root
then solve the quadratic remainder

Answer 2

as the last term x = -3 could be a zero
is f(-3) = 0?

Answer 3

take a guess such that

x = g3 + 3g2 - 3; and let the next guess be equal to x and plug it again .... this should converge to one of the roots

Answer 4

* as the last term = -3 , x = -3 could be a zero

Answer 5

f(x) = x3 - 6x2 + 9x
