Answer 1

Answer:

(x - 8y/3) (x + 2y)

Step-by-step explanation:

(x - y/3)² - 49y²/9

= (x - y/3)² - 7²y²/3²

=(x - y/3)² - (7y/3)²

as we know, a² - b² = (a - b)(a + b)

therefore:

[(x - y/3) - (7y/3)] [(x - y/3) + (7y/3)]

= (x - y/3 - 7y/3) (x - y/3 + 7y/3)

= (x - 8y/3) (x + 6y/3)

=(x - 8y/3) (x + 2y)
