Answer:
B
Step-by-step explanation:
x² - 24x + 144
consider the factors of the constant term (+ 144) which sum to give the coefficient of the x- term (- 24)
the factors are - 12 and - 12 , since
- 12 × - 12 = + 144 and - 12 - 12 = - 24 , then
x² - 24x + 144 = (x - 12)(x - 12) = (x - 12)²
Answer:
B
Step-by-step explanation:
Given :
x² - 24x + 144
Splitting the middle term :
x² - 12x - 12x + 144
x (x - 12) - 12 (x - 12)
(x - 12) (x - 12)
(x - 12)²
