Q:
# If x = 1 is a zero of the polynomial function f(x) = 3x3 − 8x2 + 3x + 2, which of the following is another zero of f(x)? x = 2 x = −2 x = −1 x = 3

Accepted Solution

A:

divide 3x^3 -8x^2+3x + 2 by (x - 1)

THis gives the quotient 3x^2 - 5x - 2

3x^2 - 5x - 2 = (3x + 1)(x - 2 )

so x = 2 is another root

Its the first choice
