No suggestions here. You should be doing your own homework. It's the only way to learn it.

Besides that, how are you going to be certain that the answers that you may receive here are the right ones?

This is the difference of two squares:
= (5x + 9y) (5x - 9y)
Thanks Ms. Samuals for teaching me that.

(5x)2 -(9y)2

(5x-9y)(5x+9y)

(a-b)(a+b)=a2-b2
