Answer 2

Answer:

$(x + \frac{6y}{3} )(x - \frac{8y}{3} )$

Step-by-step explanation:

$(x - \frac{y}{3})^{2} - \frac{49y ^{2} }{9 } \\ (x - \frac{y}{3} )^{2} - ( \frac{7y}{3} ) ^{2} \\ we \: know \: {x}^{2} - {y}^{2} = (x + y)(x - y) \\ (x - \frac{y}{3} + \frac{7y}{3} )(x - \frac{y}{3 } - \frac{7y}{3} ) \\ (x + \frac{6y}{3} )(x - \frac{8y}{3} )$

There you go
