Answer:

The answer to your question is:

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".
