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.

densk [106]

Teachers often all this problem a donut problem because it’s like the donut hole getting cut out of the middle. The way that you solve this is to find the area of the whole yard and subtract the area of the fountain. Since they are rectangles we’re going to use A = LW
Area of yard - Area of fountain
A = (8x)(9x) - (2x)(5x)
A = 72 x^2. - 10 x^2
A 62 x^2
