guyyss plzz factorise 3x³-x²-3x-1

Answer 1

Factor:

In term of Factor to factor a number means to the break it up into the numbers that can be multiplied together and to get the original number. Sometimes the numbers can be factored into different combinations.

Let us consider we are given 3x2- x2-3x+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)
