What is the factored form of the expression k^2 - 9h^2

The equation which is supposed to help you is this one:
a^2 - b^2 = (a+b) (a-b)

So, what we need to do here is apply this equation:
k^2 - 9h^2 = 
k * k - (3h)^2 =
(k + 3h) (k - 3h)

I am not exactly the best at math, but I am inclined to think it’s true, I am of reasonable intelligence. (Also, may I note that if you are at this point in math, that you should know this. Not saying that you don’t, but whatever)

Hope this helps you
