To factor the quadratic expression -x² + 8x - 12, we can follow these steps:

Start with the quadratic expression: -x² + 8x - 12.

To factor out -1, we can rewrite the expression as: -1(x² - 8x + 12).

Now, let's factor the quadratic expression inside the parentheses: x² - 8x + 12.

To factor this quadratic expression, we need to find two numbers that multiply to give 12 and add up to -8 (the coefficient of the midd...
