To factor the polynomial 10m³ + 30m² + 30m + 90, let's follow the factor by grouping method:

Step 1: Group the terms: (10m³ + 30m²) + (30m + 90)

Step 2: Factor out the common factor from each group:
In the first group, we can factor out 10m²: 10m²(m + 3).
In the second group, we can factor out 30: 30(m + 3).

Now, we have: 10m²(m + 3) + 30(m + 3)
