Here's how to perform polynomial long division to find the quotient and remainder:
```
x^2 - 2x + 8
------------------
x^2 + 2x - 5 | x^4 + 0x^3 - x^2 + 3x - 7
x^4 + 2x^3 - 5x^2
------------------
-2x^3 + 4x^2 + 3x
-2x^3 - 4x^2 + 10x
------------------
8x^2 - 7x - 7
8x^2 + 16x - 40
------------------
-23x + 33
```
Therefore:
* **Quotient:** x² - 2x + 8
* **Remainder:** -23x + 33
