The answer is A. x³ - x² - 17x + 12.
To multiply a binomial by a trinomial, we multiply each term in the first polynomial by each term in the second polynomial.
Multiplying the first term then the second term of the first polynomial by each term in the second polynomial, we now have
(x+4)(x² - 5x + 3) = x³ - 5x² + 3x + 4x² - 20x + 12
Combining like terms to simplify and get the product equal to:
(x+4)(x² - 5x + 3) = x³ - 5x² + 4x² + 3x - 20x + 12
= x³ - x² - 17x + 12
B. Yes, because all of the pairs represent the same ratio

Convert it into the y=a(x-h)+k form and the values of h and k are your vertex.
You can convert by completing the square method.
You need to distribute the 4, so you'll end up with:
4n-16=-12
Then, add 16 to both sides.
4n-16+16=-12+16
4n=4
Divide by 4 on both sides.
4/4n=4/4
n=1
