Question

⅓(6x +15y)² (6x-15y)²
simplify the following
algebric expression
step by step explanation​

Answer 1

Answer:

⅓ (6x² + 2(6x)(15y) + 15y²) (6x² - 2(6x)(15y) + 15y²)

by using identity (x + y)² = x² + 2(x)(y) + y² and

(x - y)² = x² - 2(x)(y) + y² respectively.

⅓ (6x² + 180xy+ 15y²) (6x² - 180xy + 15y²)

⅓ (6x² + 15y²) (6x² + 15y²)

⅓ (6x² + 15y²)² ( by using : (x² + y²) = (x + y) (x - y)

Hope it helps.......
