Write the polynomial in factored form.

x^3-3x^2-10x

The polynomial x^3 - 3x^2 - 10x can be factored as follows:

x(x^2 - 3x - 10)

Now, we need to factor the quadratic expression x^2 - 3x - 10. This can be done by finding two numbers whose product is -10 and whose sum is -3. These numbers are -5 and 2.

Thus, the factored form of the polynomial x^3 - 3x^2 - 10x is:

x(x - 5)(x + 2)
