Answer 2

Let's simplify the equation step by step:

(x + 2)(x² - 2x + 4) = x(x - 1)(x + 1) + 2x

First, let's expand the left side of the equation using the distributive property:

(x + 2)(x² - 2x + 4) = x(x - 1)(x + 1) + 2x x(x² - 2x + 4) + 2(x² - 2x + 4) = x(x - 1)(x + 1) + 2x x³ - 2x² + 4x + 2x² - 4x + 8 = x(x - 1)(x + 1) + 2x

Now, let's simplify the expression further:

x³ - 2x² + 4x + 2x² - 4x + 8 = x(x - 1)(x + 1) + 2x x³ + (2x² - 2x²) + (4x - 4x) + 8 = x(x - 1)(x + 1) + 2x x³ + 8 = x(x - 1)(x + 1) + 2x

The equation is simplified to x³ + 8 = x(x - 1)(x + 1) + 2x.
