In order to find the quotient and remainder of the division, let's divide the polynomials doing the following steps:

x³ divided by x: .

x² times (x + 2): x³ + 2x²

x³ + 6x² + 17x + 11 minus (x³ + 2x²): 4x² + 17x + 11

4x² divided by x: 4x

4x times (x + 2): 4x² + 8x

4x² + 17x + 11 minus (4x² + 8x): 9x + 11

9x divided by x: 9

9 times (x + 2): 9x + 18

9x + 11 minus (9x + 18): -7

Therefore the quotient is x² + 4x + 9 and the remainder is -7

Correct option: first one.
