Answer 5

(x 2 + 6x + 9)(3x - 1)
=3x^3+18x^2+27x-x^2-6x-9
=3x^3+17x^2+21x-9
option A

Answer 6

FOIL is out, (x^2(3x -1)) + (6x(3x - 1)) + (9(3x - 1))

\(\ \sf \color{blue}{x^2}(\color{red}{3x - 1}) \implies (\color{blue}{x^2} \times\color{red}{3x}) + (\color{blue}{x^2} \times \color{red}{-1}) = 3x^3 + (-x^2) = 3x^3 - x^2 \)
