1. Identify that we have a perfect cube minus another perfect cube, example: first term - second term.2. Rewrite the problem as: (first term)³ - (second term)³3. Factor the expression into the first term minus second term, times the first term² plus the first term multiplied by the second term plus the second term², like this: (first term - second term) [(first term)² + (first term X second term) + (second term)²]4. Rewrite the problem as: (first term - second term) (first term² + total of 1st & 2nd term + second term²)
