To factor the expression 3x^2 - 6x - 9, first, we look for a common factor among all terms, which is 3. Factoring out 3, we get:
3(x^2 - 2x - 3)
Now, we need to factor the quadratic expression inside the parentheses. We're looking for two numbers that multiply to -3 and add up to -2 (the coefficient of the x-term). These numbers are -3 and 1.
So, we can rewrite the expression as:
3(x - 3)(x + 1)
