Answer 2

Of course, I'd be happy to help! It looks like you have an expression that's the product of three factors: $(x-1)(x+1)(x-3)$. To simplify this expression, you can use the distributive property and multiply the factors together. Here's how you can do it step by step:

1. Multiply the first two factors: $(x-1)(x+1)$

   Using the formula $(a+b)(a-b) = a^2 - b^2$, you can apply it here with $a = x$ and $b = 1$:

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

2. Multiply the result from step 1 by the third factor: $x^2 - 1$ multiplied by $(x-3)$

   Distribute $x^2 - 1$ across the terms in $(x-3)$:

   $x^2(x-3) - 1(x-3) = x^3 - 3x^2 - x + 3$

So, the simplified expression is $x^3 - 3x^2 - x + 3$.
