Answer:
Option A. (9x - 12)²
Step-by-step explanation:
We will factorize the given polynomial into perfect square.
The polynomial is 81x²- 216x + 144
We will take 9 common out of this polynomial first
81x² - 216x + 144 = 9(9x² - 24x + 16)
= 9[(3x)² - 2(3)(4)x + 4²]
= 9[(3x - 4)²
= 3²(3x - 4)²
= (9x - 12)²
Therefore, Option A. (9x - 12)² is the answer.
Answer:
A.
Step-by-step explanation:
We need to determine whether the polynomial can be factored into perfect squares. If so, factor the polynomial. Otherwise, select that it cannot be factored into a perfect square.
Hence choice A. is correct.
