Hey there! :)
Answer:
2u³ (5u + 1)(u + 3)
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!
