What are the possible integral zeros of #P(s)=s^3+4s^2-15s-18#?
The possible integral zeros of the equation will be the divisors of the isolated number divided by the coefficient of the largest degree in the polynomial:
The divisors of 18 are
Of course, you should divide these numbers by 1, which is the coefficient of the highest degree member of the polynomial.
The question is not answered until we find the values of the divisors that when substituted in the function it equates to
The result should be
So the numbers that result in
