Answer:

The required factors are: x, (x + 6) and (x - 3).

Step-by-step explanation:

As per the question,

The given polynomial is:

x^{3}+3x^{2}-18x

Now,

BY factorization, we get

x^{3}+3x^{2}-18x

=x(x^{2}+3x-18)

By splitting the mid-term, that is split 3x like:

3x = 6x - 3x

Therefore,

x(x^{2}+6x-3x-18)

Now on further solving by taking common factor out, we get

=x[x(x+6)-3(x+6)]

=x(x+6)(x-3)

Therefore, the given second polynomial (x - 4), is not a factor of given polynomial x^{3}+3x^{2}-18x.

Hence, the given polynomial has three factor x, (x + 6) and (x - 3).
