Answer 2

It seems like you're asking about the expansion of the expression $(x - 2)(x + 1)(x + 2)$. To expand this expression, you can use the distributive property, also known as FOIL (First, Outer, Inner, Last). Here's how you can do it step by step:

$(x - 2)(x + 1)(x + 2)$

1. First, apply the distributive property to the first two factors: $(x - 2)(x + 1) = x^2 + x - 2x - 2 = x^2 - x - 2$

2. Now, multiply the result from step 1 by the third factor: $(x^2 - x - 2)(x + 2) = x^3 + 2x^2 - x^2 - 2x - 2x - 4 = x^3 + x^2 - 4x - 4$

So, the expanded form of the expression $(x - 2)(x + 1)(x + 2)$ is $x^3 + x^2 - 4x - 4$.
