Answer 3

To simplify the expression $(x-3)^2 - (x-1)(x-4) + (x-2)(x+2)$, you can follow these steps:

1. Expand each term in the expression:

   $(x-3)^2 = x^2 - 6x + 9$

   $(x-1)(x-4) = x^2 - 5x + 4$

   $(x-2)(x+2) = x^2 - 4$

2. Substitute these expanded forms back into the original expression:

   $x^2 - 6x + 9 - (x^2 - 5x + 4) + (x^2 - 4)$

3. Now, perform the arithmetic operations:

   $x^2 - 6x + 9 - x^2 + 5x - 4 + x^2 - 4$

4. Simplify by combining like terms:

   $-6x + 9 - 4 + 5x - 4$

5. Combine the terms with $x$:

   $-6x + 5x = -x$

6. Combine the constants:

   $9 - 4 - 4 = 1$

So, the simplified expression is $-x + 1$.
