Itu X pangkat 2 dikurangi dengan x bukan 2-x

I understand now, you're asking about the expression \( x^2 - x \), which is different from what I previously explained (which was related to \( 2 - x \)).

Let's discuss the expression \( x^2 - x \):

### Expression: \( x^2 - x \)

This expression represents a quadratic function. Here's a detailed breakdown:

1. **Expression**:
   \[
   x^2 - x
   \]

2. **Factoring**:
   You can factor this quadratic expression by taking \( x \) as a common factor:
   \[
   x^2 - x = x(x - 1)
   \]
   This shows that the roots of the equation \( x^2 - x = 0 \) are \( x = 0 \) and \( x = 1 \).

3. **Vertex**:
   The vertex of the parabola represented by \( y = x^2 - x \) can be found using the vertex formula:
   \[
   x = -\frac{b}{2a}
   \]
   Here, \( a = 1 \) and \( b = -1 \), so:
   \[
   x = -\frac{-1}{2 \times 1} = \
