Recognize Difference of Squares: Step Title: Recognize the Difference of SquaresConcise Step Description: Identify that the expression is a difference of squares, which can be factored into the product of a sum and difference.Step Calculation: Recognize that 1−d6 can be written as 12−(d3)2.
Apply Squares Formula: Step Title: Apply the Difference of Squares FormulaConcise Step Description: Use the difference of squares formula a2−b2=(a+b)(a−b) to factor the expression.Step Calculation: Factor 12−(d3)2 into (1+d3)(1−d3).
Factor Difference of Squares: Step Title: Factor the Resulting Difference of SquaresConcise Step Description: Recognize that 1−d3 is also a difference of cubes and can be further factored.Step Calculation: Factor 1−d3 using the difference of cubes formula a3−b3=(a−b)(a2+ab+b2) to get (1−d)(1+d+d2).
Combine Factored Forms: Step Title: Combine the Factored FormsConcise Step Description: Combine the factored forms from the previous steps to write the completely factored expression.Step Calculation: The completely factored form is (1+d3)(1−d)(1+d+d2).
