It is a difference of two squares, in the form a^2-b^2

Take the square root of both terms, which will be 3k and 5b. Then write them in the form

(a-b)(a+b)

Your factored form will be

(3k+5b)(3k-5b)

9kÂ² - 25bÂ²
= 3Â²kÂ² - 5Â²bÂ²
= (3k + 5b)(3x - 5b)

It's the difference of two perfect squares, right?

(3k - 5b)(3k + 5b)

(3k)^2-(5b)^2
=(3k+5b)(3k-5b)
