To factor the quadratic expression  -x² + 13x - 12, we can follow these steps:

Start with the quadratic expression: -x² + 13x - 12

To factor out -1, we can rewrite the expression as: -1(x² - 13x + 12)

Now, let's factor the quadratic expression inside the parentheses: x² - 13x + 12

To factor this quadratic expression, we need to find two numbers that multiply to give 12 and add up...
