Hey there! :)

2u³ (5u + 1)(u + 3)

Step-by-step explanation:

Begin by factoring a common factor from each term. In this instance, it would be 2u³:

2u³ (5u² + 16u + 3)

Factor the polynomial inside the parenthesis. The factors must add up to 16u, and multiply to become 3. We get:

2u³ (5u + 1)(u + 3)

This is the equation factored entirely!
