To factor the polynomial 2x³ + 10x² - 6x - 30, we can use the grouping method:

Step 1: Group the terms: (2x³ + 10x²) - (6x + 30)

Step 2: Factor out the common factor from each group:
In the first group, we can factor out 2x²: 2x²(x + 5).
In the second group, we can factor out 6: 6(x + 5).

Now, we have: 2x²(x + 5) - 6(x + 5)

Step 3: Notice that (
