e) \( (2 t-1)(2 t+1) \)

Did you know that the expression \( (2t-1)(2t+1) \) represents a special algebraic product known as the difference of squares? When you expand it, you get \( 4t^2 - 1 \). This beautiful identity is a powerful tool in algebra, showing how two binomials can simplify a quadratic expression! When working with expressions like \( (2t-1)(2t+1) \), a common mistake is to forget to apply the distributive property correctly. It’s easy to make errors, like mixing up the signs or accidentally skipping a term. Always double-check your work: you might even find a hidden gem or an unexpected simplification!
