To represent the polynomial \(2x^2 - 9x - 18\) using algebra tiles, we need to break it down into components of \(x^2\), \(x\), and constant terms. Here's how it can be done:

1. **\(2x^2\) Tiles:**
   - Represent two \(x^2\) tiles. These are large squares that each represent \(x^2\).

2. **\(-9x\) Tiles:**
   - Represent nine negative \(x\) tiles. These are rectangles (or bars) that each represent \(-x\).

3. **\(-18\) Constant Tiles:**
   - Represent eighteen negative unit tiles. These are small squares that each represent \(-1\).

Now, putting these together:

- You have 2 large squares representing \(2x^2\).
- You have 9 rectangles representing \(-9x\).
- You have 18 small squares representing \(-18\).

If you visualize these tiles on a grid or arrange them physically with algebra tiles, you would have a mix of positive and negative tiles corresponding to the polynomial \(2x^2 - 9x - 18\).

Would you like a detailed visual representation or have any specific questions regarding this?
