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 as (a2−b2)=(a−b)(a+b).Step Calculation: Recognize that b9 is (b3)3 and 1 is 13, so the expression can be written as (b3)3−13.Step Output: Expression is a difference of two squares.
Apply Squares Formula: Step Title: Apply the Difference of Two Squares FormulaConcise Step Description: Apply the difference of two squares formula to factor the expression.Step Calculation: Factor b9−1 as (b3−1)(b3+1).Step Output: Factored form is (b3−1)(b3+1).
Factor First Term Further: Step Title: Factor the First Term FurtherConcise Step Description: Recognize that the first term (b3−1) is also a difference of two squares and can be factored further.Step Calculation: Factor b3−1 as (b−1)(b2+b+1).Step Output: Factored form of the first term is (b−1)(b2+b+1).
Factor Second Term Further: Step Title: Factor the Second Term FurtherConcise Step Description: Recognize that the second term b3+1 is a sum of two cubes and can be factored using the sum of cubes formula.Step Calculation: Factor b3+1 as (b+1)(b2−b+1).Step Output: Factored form of the second term is (b+1)(b2−b+1).
Combine Factored Forms: Step Title: Combine the Factored FormsConcise Step Description: Combine the factored forms of both terms to get the completely factored expression.Step Calculation: The completely factored form is (b−1)(b2+b+1)(b+1)(b2−b+1).Step Output: Completely factored form is (b−1)(b2+b+1)(b+1)(b2−b+1).
