Keenan Russell · Answer 1

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

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 = 2x = - 2x = - 1x = 3

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
