Answer:

Explanation:
In order to find the product of the polynomials 3x² + 3 and 4x² - 1, we can use the distributive property to multiply each term in the first polynomial by each term in the second polynomial.

Use the distributive property to multiply each term in the first polynomial by each term in the second polynomial:

Now, perform the multiplications:




Now, combine the like terms:

Combine the terms with the same exponent:

Now, simplify further by combining like terms:

So, the product of 3x² + 3 and 4x² - 1 is:
