1. Let's clarify the problem you are referring to by restating the step 3 expression or equation. 2. Identify the expressions or operations involved in step 3. 3. Break down the operations step-by-step, such as simplifying terms, factoring, expanding, or applying algebraic rules. 4. Show intermediate calculations explicitly to see how the expression transforms from step 2 to step 3. 5. Explain each transformation in simple terms, for example, "we combined like terms," "we factored out a common factor," or "we applied the distributive property." 6. If you provide the exact expressions from step 2 and step 3, I can demonstrate the detailed algebraic manipulation. 7. Understanding these steps will help you see why the expression looks the way it does in step 3. Please share the exact expressions or the problem context for a precise explanation.
