To apply the difference of two squares formula, follow these steps:
1. Identify the two terms that are perfect squares. These terms should be in the form of "a^2" and "b^2" where "a" and "b" are variables or constants.
2. Write the given expression as a difference of two squares. For example, if the expression is "x^2 - 4", you can write it as "(x)^2 - (2)^2".
3. Apply the formula: (a^2 - b^2) = (a + b)(a - b)
4. Substitute the values of "a" and "b" from the given expression into the formula. In our example, it would be (x + 2)(x - 2) = x^2 - 4.
5. Simplify the expression if possible.
By following these steps, you can easily apply the difference of two squares formula to simplify algebraic expressions.
