To factor the polynomial 8m³ + 20m² + 20m + 50, let's follow the factor by grouping method:

Step 1: Group the terms: (8m³ + 20m²) + (20m + 50)

Step 2: Factor out the common factor from each group:
In the first group, we can factor out 4m²: 4m²(2m + 5).
In the second group, we can factor out 10: 10(2m + 5).

Now, we have: 4m²(2m + 5) + 10(2m + 5)

Step 3: Notice that (2m + 5)...
