What methods have you been taught to solve such problem?

Have you been taught "rational root" theorem?

Hint:

Try all the factors (positive and negative) of 32 as a solution.

Please show your work, indicating exactly where you are stuck - so that we may know where to begin to help you.

\(\displaystyle f(x) \ = \ x^3-24x+32\)

\(\displaystyle Hint: \ f(4) \ = \ 0.\)
