Answer:
(x - 12)(x - 4)
Step-by-step explanation:
Given
x² - 16x + 48
Consider the factors of the constant term (+ 48) which sum to give the coefficient of the x- term (- 16)
The factors are - 12 and - 4, since
- 12 × - 4 = + 48 and - 12 - 4 = - 16 , thus
x² - 16x + 48 = (x - 12)(x - 4) ← in factored form
