The highlighted step contains an error. Step 1: The identity ^3 + ^3 = + is incorrect. The correct identity for the sum of cubes is: ^3 + ^3 = ( + )(^2 - + ^2) We also know that ^2 + ^2 = ( + )^2 - 2. Substituting this into the sum of cubes identity gives: ^3 + ^3 = ( + )(( + )^2 - 3) Step 2: Let's correctly calculate the sum
