Answer:

The answer to your question is      12n² + 6n - 3

Step-by-step explanation:

Polynomial

                   3(4n² + 2n - 1)

Distributive property, this property lets us multiply a sum by multiplying each term of the sum separately and if possible simplify like terms.

Solution

                 3(4n²) + 3(2n) - 3(1)

                 12n² + 6n - 3
