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
