Question

factorise :3x³-x²-3x+1

Answer 1

So here we are taking a common in the given equation x2(3x-1) – (3x-1)
(3x-1) (x2-1)          1
As we known that we can solve further of this equation (x2-1)
(a2+b2) = (a+b) (a-b)
So here we are applying this formula on this equation (x2-1).
Thus we have (x+1) (x-1)
Now we are putting in the eq-1
So it is a required answer (3x-1) (x+1) (x-1)

Answer 2

(x-1)(3x² + 2x-1) 
is the fator of your question
