Ok
3x^2 - 75y^2
First, factor out the 3:
3 (x^2 - 25y^2)
Then, you can factor the parenthesis. Remember, you can also write it like this : (X^2 - 25y^2 +0)
3 (x + 5y)(x - 5y)
And that's it!
Hope this helps!

First, find the GCF (3)
then take the 3 out f the equation and see what you have left.
3(x^2-25y^2)
then split up the equation (factor it). since there is a minus in the problem, one of the parenthesis will be addition, and the other, subtraction.
3(x+5y)(x-5y)
