Find the product of the polynomials x2 + 5x and 2x + 10

  1. 10x2 + 30x + 10

  2. 12x2 + 15x + 10

  3. 10x2 + 15x

  4. 12x2 + 50x + 10

The correct answer is: 12x2 + 50x + 10

To find the product of two polynomials, you must multiply each term in the first polynomial by each term in the second polynomial and then combine like terms. Option A does not have the correct number of terms. Option B is missing the term 50x. Option C is missing the term 10. Option D has all the terms present and in the correct order, resulting in the correct product of 12x2 + 50x + 10.
