Answer 1

what do you mean????????????

Answer 2

Answer:

PLEASE BRAINLIEST MY ANSWER

Step-by-step explanation:

x³ + y³ = (x+y) (x² -xy+y ²)​

RHS = (x+y) (x² -xy+y ²)​

       = x (x² -xy+y ²) +​ y (x² -xy+y ²)​

       = x³ - x²y + xy² + x²y - xy² + y³

       = x³ - x²y + x²y + xy² - xy² + x³

       = x³ + 0 + 0 + y³

       = x³ + y³

RHS = LHS

x³ + y³ = (x+y) (x² -xy+y ²)​ ------------- (is proved)
