Recognize Difference of Two Squares: Step Title: Recognize the Difference of Two SquaresConcise Step Description: Identify that the expression is a difference of two squares, which can be factored using the formula a2−b2=(a−b)(a+b).Step Calculation: Recognize that d9 is (d3)3 and a9 is (a3)3, so the expression is a difference of two cubes, which can be factored using the formula a3−b3=(a−b)(a2+ab+b2).Step Output: The expression is a difference of two cubes.
Apply Cubes Formula: Step Title: Apply the Difference of Two Cubes FormulaConcise Step Description: Apply the difference of two cubes formula to factor the expression.Step Calculation: Using the formula a3−b3=(a−b)(a2+ab+b2), we get (d3−a3)((d3)2+d3∗a3+(a3)2).Step Output: Factored expression as (d3−a3)(d6+d3∗a3+a6).
Factor First Term Further: Step Title: Factor the First Term FurtherConcise Step Description: Recognize that the first term d3−a3 is also a difference of two cubes and can be factored further.Step Calculation: Using the formula a3−b3=(a−b)(a2+ab+b2) again, we get (d−a)(d2+da+a2).Step Output: Factored expression as (d−a)(d2+da+a2).
Combine Factored Terms: Step Title: Combine the Factored TermsConcise Step Description: Combine the factored terms from the previous steps to get the completely factored expression.Step Calculation: The completely factored expression is (d−a)(d2+da+a2)(d6+d3a3+a6).Step Output: Completely factored expression.
