Answer:

A. $=(9x-12)^2$

Step-by-step explanation:

We need to determine whether the polynomial $81x^2-216x+144$ can be factored into perfect squares. If so, factor the polynomial. Otherwise, select that it cannot be factored into a perfect square.

$81x^2-216x+144$

$=9(9x^2-24x+12)$

$=9(9x^2-12x-12x+12)$

$=9(3x(3x-4)-4(3x-4))$

$=9(3x-4)(3x-4)$

$=9(3x-4)^2$

$=3^2(3x-4)^2$

$=(3(3x-4))^2$

$=(9x-12)^2$

Hence choice A. $=(9x-12)^2$ is correct.
