1. **State the problem:** Factor the given expression. Since no specific expression was provided, let's consider a general approach to factoring. 2. **Formula and rules:** Factoring involves rewriting an expression as a product of simpler expressions. Common methods include: - Factoring out the greatest common factor (GCF) - Factoring trinomials - Difference of squares: $$a^2 - b^2 = (a - b)(a + b)$$ - Factoring by grouping 3. **Example:** Suppose the expression is $$x^2 - 9$$. 4. **Apply difference of squares:** $$x^2 - 9 = x^2 - 3^2 = (x - 3)(x + 3)$$ 5. **Explain:** We recognize the expression as a difference of squares and factor it accordingly. If you provide a specific expression, I can factor it step-by-step for you.
