The book doesn't say if I should either factor it solve it or both. But it has to be one of those.
Here is the equation:
25x^4-9y^2
It is NOT an equation since it DOESN'T have an "equals" sign! Therefore, it needs to be FACTORED!

Hint in FACTORING these types of expressions: It's a DOTS (Difference of Two Squares) expression.
