The expression from the image is:

$\frac{x^3 - 2x^2 + x - 1}{x - 1} + \sqrt{4x^2 - 12x + 9}$

Let me help you simplify and solve it step by step:

Step 1: Simplify the rational expression.

The first term is $\frac{x^3 - 2x^2 + x - 1}{x - 1}$. This can be simplified by performing polynomial division.

Step 2: Simplify the square root.

The second term is $\sqrt{4x^2 - 12x + 9}$, which can potentially be factored before simplifying the square root.
