Answer 1

x^3 + 5x^2 + 2x - 8

Answer 2

are you sure its right

Answer 3

Apologies for the mistake. Let's reevaluate the product:

(x + 2)(x^2 + 3x - 4)

Expanding the product:
= x(x^2 + 3x - 4) + 2(x^2 + 3x - 4)
= x^3 + 3x^2 - 4x + 2x^2 + 6x - 8
= x^3 + 5x^2 + 2x - 8

Therefore, the correct simplification of the product into standard form is:
x^3 + 5x^2 + 2x - 8
