1. **State the problem:**
We want to find the expression for the area of a large rectangle with dimensions $2x - 2$ (top side) and $x + 1$ (left side), from which a smaller rectangle with dimensions $x$ (width) and $x - 2$ (height) is removed.
2. **Write the formula for the area of rectangles:**
The area of a rectangle is given by multiplying its length by its width.
3. **Calculate the area of the large rectangle:**
$$\text{Area}_{\text{large}} = (2x - 2)(x + 1)$$
4. **Calculate the area of the smaller rectangle to be removed:**
$$\text{Area}_{\text{small}} = x(x - 2)$$
5. **Write the expression for the remaining area:**
$$\text{Area}_{\text{remaining}} = (2x - 2)(x + 1) - x(x - 2)$$
6. **Expand the products:**
$$ (2x - 2)(x + 1) = 2x^2 + 2x - 2x - 2 $$
$$ x(x - 2) = x^2 - 2x $$
7. **Substitute and simplify:**
$$ 2x^2 + 2x - 2x - 2 - (x^2 - 2x) = 2x^2 + 2x - 2x - 2 - x^2 + 2x $$
8. **Combine like terms:**
$$ 2x^2 - x^2 + 2x - 2x + 2x - 2 = x^2 + 2x - 2 $$
**Final answer:**
$$\boxed{x^2 + 2x - 2}$$
This expression represents the area of the large rectangle with the smaller rectangle removed.
