Explanation opens after your attempt
A. ( (x+3y)(x-3y)2 )
Concept
The expression \(x^3+27y^3\) has factor ((x+3y)). The inside becomes \(x^2-12xy+9y^2\), giving ((x-3y)2).
Why this answer is correct
The correct answer is A. ( (x+3y)(x-3y)2 ). The expression \(x^3+27y^3\) has factor ((x+3y)). The inside becomes \(x^2-12xy+9y^2\), giving ((x-3y)2).
