Hello!
Answer:

Explanation:
→ We want to solve this equation:

→ It's a 3rd degree equation because it's on the form ax³ + bx² + cx + d = 0.
→ To solve a 3rd degree equation, let's factorize this equation:






→ So now he have 3 equations to find the solutions:



→ So the solutions are:
-4, 2, 3
Conclusion:
The solutions of the equation x³ - x² - 14x + 24 = 0 are -4, 2 and 3.
