    Here you go:

    a) f(x)= (3x-1)(x+2)
    This is factoring. It helps you find the zeros if you set this equal to zero. You can clearly identify what the zeros are.

    b) (3x-1)(x+2)=0
    x=1/3, x=-2

    Plug those back into the equation to see if they work. In this case they do so those are your answers.
