To factor x^2 - 8x + 15, we need to find two numbers that multiply to 15 (the constant term) and add up to -8 (the coefficient of the middle term).

Factors of 15: (1, 15), (-1, -15), (3, 5), (-3, -5)

Out of these pairs, the pair (-3, -5) has a sum of -8.

Therefore, x^2 - 8x + 15 can be factored as (x - 3)(x - 5).
