Answers: Choices A and C

Factors are 9x-6 and 9x+6

=================================================

Explanation:

We use the difference of squares rule

m^2 - n^2 = (m-n)(m+n)

In this case we have

  • m = 9x
  • n = 6

So,

m^2 - n^2 = (m-n)(m+n)

(9x)^2 - 6^2 = (9x-6)(9x+6)

81x^2 - 36 = (9x-6)(9x+6)
