Answer:

(x-2)(x+3)(x-4)

Explanation:

Given factor is x-2 , so

The synthetic division table is:

The remainder zero proves that x-2 is a factor of x^(3 )-3x^2-10x-24.

The division gives us the quotient.

(x^(3 )-3x^2-10x-24)/(x-2)=x^2-x-12

The quotient is a quadratic equation which can easily be factorized.

= x^2-x-12

=x^2-4x+3x-12

=x^2-4x+3x-12

=x(x-4)+3(x-4)

=(x+3)(x-4)

So,

x^(3 )-3x^2-10x-24=(x-2)(x+3)(x-4)
