To factorize the expression 25x² - 36y², we can recognize it as a difference of squares.
We know that
25x² can be written as (5x)² and
36y² can be written as (6y)².
The expression
25x² - 36y² can be rewritten as (
5x)² - (
6y)².
Now we can use the difference of squares formula, which states that a² - b² = (a + b)(a - b).
Applying this formula, we have: (
5x)² - (
