Recognize Difference of Cubes: Step Title: Recognize the Difference of Two CubesConcise Step Description: Identify that the expression is a difference of two cubes.Step Calculation: The expression 64w9−s9 can be written as (4w3)3−(s3)3, which is a difference of two cubes.Step Output: Expression rewritten as a difference of two cubes.
Apply Cubes Formula: Step Title: Apply the Difference of Two Cubes FormulaConcise Step Description: Use the formula a3−b3=(a−b)(a2+ab+b2) to factor the expression.Step Calculation: Let a=4w3 and b=s3. Then, apply the formula to get (4w3−s3)((4w3)2+(4w3)(s3)+(s3)2).Step Output: Factored expression using the difference of two cubes formula.
Simplify Factored Expression: Step Title: Simplify the Factored ExpressionConcise Step Description: Simplify the terms in the factored expression.Step Calculation: Simplify (4w3−s3)(16w6+4w3s3+s6).Step Output: Simplified factored expression.
Check Further Factoring: Step Title: Check for Further FactoringConcise Step Description: Check if the terms (4w3−s3) and (16w6+4w3s3+s6) can be factored further.Step Calculation: The term (4w3−s3) is a difference of cubes again and can be factored further. The term (16w6+4w3s3+s6) cannot be factored further.Step Output: Determination that (4w3−s3) can be factored further.
Factor Cubes Again: Step Title: Factor the Difference of Cubes AgainConcise Step Description: Apply the difference of cubes formula to the term 4w3−s3.Step Calculation: Let a=4w and b=s. Then, apply the formula to get \(4w - s)((4w)^2 + (4w)(s) + s^2)\.Step Output: Factored expression \(4w - s)(16w^2 + 4ws + s^2)\.
Combine Factored Terms: Step Title: Combine All Factored TermsConcise Step Description: Combine the factored terms to write the final factored expression.Step Calculation: The final factored expression is (4w−s)(16w2+4ws+s2)(16w6+4w3s3+s6).Step Output: Final factored expression.
