The answer to your question is:

Step-by-step explanation:

I don't know if you forgot the power in the second polynomial and the coefficients in the answers.                    

       (x + 2)(x² - 7x + 4) = x³  - 7x² + 4x + 2x²  - 14x + 8

                                   = x³ - 5x² - 10x + 8

Α. x3 - 7x2 + 4x + 8

Β. x - 5x2 + 4x + 8

C. 3 - 5χ2 - 10x + 8          It could be letter C the answer but the first term

D. x3 - 7x2 - 10x + 8       do not have "x".
