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

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

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

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

To factor this quadratic expression, we need to find two numbers that multiply to give -12 and add up to 1 (the coefficient of...
