TO FACTORISE :-
SOLUTION :-
We can easily factorise it by using Factor Theorem.
By applying factor theorem 1 is the zero of the polynomial so,
Hence, x - 1 is a factor of p(x)
We can divide it with p(x) to get the factor and remainder zero by using factor Theorem.
Now after dividing we got a quadratic factor which can be factorise again by middle term factorisation.
HENCE, THE CUBIC POLYNOMIAL IS FACTORISED.
