Recognize: Recognize the numerator as a cubic polynomial and the denominator as a difference of cubes.Numerator: x3−3x2y+3xy2−y3Denominator: x3−y3
Factorize: Factorize the numerator and denominator.Numerator: (x−y)3 (using the formula a3−3a2b+3ab2−b3=(a−b)3)Denominator: (x−y)(x2+xy+y2) (using the formula a3−b3=(a−b)(a2+ab+b2))
Simplify: Simplify the expression by canceling out common factors.(x−y)3/(x−y)(x2+xy+y2)=(x−y)2/(x2+xy+y2)
