Answer:

(9p -5q)(9p +5q)

Step-by-step explanation:

The difference of squares is a special form with the factoring ...

... a^2 -b^2 = (a -b)(a +b)

Here, you have ...

  • a = 9p . . . . . . you recognize that 81p^2 = (9p)^2
  • b = 5q

so the factoring is ...

... 81p^2 - 25q^2 = (9p -5q)(9p +5q)

Answer:

(9p -5q)(9p +5q)
