Recognize Difference of Squares: Step Title: Recognize the Difference of SquaresConcise Step Description: Identify that the expression is a difference of two squares.Step Calculation: Recognize that r6 is a perfect square, as (r3)2, and 64s6 is also a perfect square, as (8s3)2.Step Output: The expression can be written as (r3)2−(8s3)2.
Apply Squares Formula: Step Title: Apply the Difference of Squares FormulaConcise Step Description: Use the difference of squares formula, which is a2−b2=(a−b)(a+b).Step Calculation: Apply the formula to the expression with a=r3 and b=8s3.Step Output: The factored form is (r3−8s3)(r3+8s3).
Factor Further if Possible: Step Title: Factor Further if PossibleConcise Step Description: Check if the two resulting binomials can be factored further.Step Calculation: Recognize that r3−8s3 is also a difference of cubes, which can be factored using the formula a3−b3=(a−b)(a2+ab+b2).Step Output: Apply the formula with a=r and b=8s to get (r−8s)(r2+8rs+64s2).
Combine Factored Forms: Step Title: Combine the Factored FormsConcise Step Description: Combine the factored forms from the previous steps to get the final factored expression.Step Calculation: The final factored form is (r−8s)(r2+8rs+64s2)(r3+8s3).Step Output: The completely factored expression is (r−8s)(r2+8rs+64s2)(r3+8s3).
