3v^3 - 6v^2 + 2v - 4
My teacher would like me to factor each completely.... I dont understand how to do this problem..... please get back to me asap

You can put this solution on YOUR website! reducing this to a quadratic by finding a root is one way to factor
possible roots are factors of 4 (±1,±2,±4) divided by factors of 3 (±1,±3)
__ a root is a value for v that makes the expression equal to zero
2 is a root __ 3(2^3)-6(2^2)+2(2)-4=0
if 2 is a root, then v-2 is a factor
(3v^3-6v^2+2v-4)/(v-2)=(3v^2+2) __ this will not factor further
so, 3v^3-6v^2+2v-4=(v-2)(3v^2+2)
