What is the factored form of this expression?

x2 − 81

Step-by-step explanation:

x² - 81 = x² - 9² = (x + 9) (x - 9)              

a² - b² = (a + b)(a - b)

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
