Factors of (2x – 3y)3 + (3y – 5z)3 + (5z – 2x)3 are :(a) 3(2

1.	Factors of (2x – 3y)3 + (3y – 5z)3 + (5z – 2x)3 are :(a) 3(2x - 3y)(3y - 5z)(5z - 2x)(b) 3(3x - 2y)(3y - 5z)(5z - 2x)(c) 3(2x - 3y)(5y - 3z)(5z - 2x)(d) 3(2x - 3y)(3y - 5z)(2z - 5x)
Answer» (a) 3(2x - 3y)(3y - 5z)(5z - 2x) Since (2x - 3y) + (3y - 5z) + (5z - 2x) = 0 (2x - 3y)³ + (3y - 5z)³ + (5z - 2x)³ = 3(2x - 3y)(3y - 5z)(5z - 2x)

Factors of (2x – 3y)3 + (3y – 5z)3 + (5z – 2x)3 are :(a) 3(2x - 3y)(3y - 5z)(5z - 2x)(b) 3(3x - 2y)(3y - 5z)(5z - 2x)(c) 3(2x - 3y)(5y - 3z)(5z - 2x)(d) 3(2x - 3y)(3y - 5z)(2z - 5x)

Answer»

(a) 3(2x - 3y)(3y - 5z)(5z - 2x)

Since (2x - 3y) + (3y - 5z) + (5z - 2x) = 0

(2x - 3y)³ + (3y - 5z)³ + (5z - 2x)³

= 3(2x - 3y)(3y - 5z)(5z - 2x)
