Answer:
(x - 6)(x - 5)
Step-by-step explanation:
Given
x² - 11x + 30
Consider the factors of the constant term (+ 30) which sum to give the coefficient of the x- term (- 11)
The factors are - 6 and - 5, since
- 6 × - 5 = + 30 and - 6 - 5 = - 11, thus
x² - 11x + 30 = (x - 6)(x - 5) ← in factored form
