To factor the polynomial 4x³ + 20x² - 12x - 60, we can use the grouping method:

Step 1: Group the terms: (4x³ + 20x²) - (12x + 60)

Step 2: Factor out the common factor from each group:
In the first group, we can factor out 4x²: 4x²(x + 5).
In the second group, we can factor out 12: 12(x + 5).

Now, we have: 4x²(x + 5) ...
