To factor the polynomial 5x³ + 25x² - 15x - 75, we can use the grouping method:

Step 1: Group the terms: (5x³ + 25x²) - (15x + 75)

Step 2: Factor out the common factor from each group:
In the first group, we can factor out 5x²: 5x²(x + 5).
In the second group, we can factor out 15: 15(x + 5).

Now, w...
