Understanding zeroes and factors of polynomials

Find all zeros. $f\left(x\right)\ =\ 3x^3+2x^2-x$  

•  $\left\{0,\ \frac{1}{3},\ -1\right\}$  

•  $\left\{0\ mult.\ 2,\ -1\right\}$  

•  $\left\{0,\ \frac{1}{3},\ -3\right\}$  

•  $\left\{0,\ -\frac{2}{3},\ \ -1\right\}$  

Find all the zeros, given that f(-3) = 0
f(x) = 2x³+5x²-6x-9

• -1,-3,-3
