1. The problem is to show that two expressions are equal by solving one and demonstrating it results in the other, and vice versa. 2. To prove two expressions are equal, we can solve one expression and simplify it to see if it matches the other expression. 3. Start by solving the first expression step-by-step, simplifying and factoring as needed. 4. After simplification, compare the result to the second expression. 5. Repeat the process by solving the second expression and simplifying it to see if it matches the first. 6. If both simplifications lead to the same expression, the two are equal. This method uses algebraic manipulation and properties such as distributive, associative, and commutative laws to verify equality.
