Divide p over (x-1) with euclidian division we get the quotient:
[tex]3x^3+2x^2-6x-4[/tex]
Note that -2/3 is also roots of the above polynomial. 
Checking:
[tex]3(-2/3)^3+2(-2/3)^2-6(-2/3)-4=0[/tex]
Dividing again with euclidian algorithm we get the quotient:
[tex]3x^3+2x^2-6x-4[/tex] over [tex]3x+2[/tex] is [tex]X^2-2[/tex].
Final factorization:
[tex]p(x)=(x-1)(3x+2)(x-\sqrt2)(x+\sqrt2)[/tex]
