Answer:
(k - 6)(k - 4)
Step-by-step explanation:
Given
k² - 10k + 24
Consider the factors of the constant term (+ 24) which sum to give the coefficient of the k- term (- 10)
The factors are - 6 and - 4, since
- 6 × - 4 = + 24 and - 6 - 4 = - 10 , thus
k² - 10k + 24 = (k - 6)(k - 4) ← in factored form
