RHS-
(x+y)(x²-xy+y²)
=x(x²-xy+y²)+y(x²-xy+y²)
=x³-x²y+xy²+x²y-xy²+y³
(CANCEL THE POSSIBLE TERMS)
=x³+y³
=LHS
therefore verified

We first verify the formula for the sum of two cubes. A) x³ + y³ = (x + y)(x² - xy + y²) B) x³ + y³ = (x - y)(x² + xy + y²) C) x³ + y³ = (x + y)(x² + xy + y²) D) x³ + y³ = (x - y)(x² - xy + y²)

Verify 1) x³+y³=(x+y)(x²-xy+y²) 2) x³-y³=(x-y)(x²+xy+y²) using some non-zero positive integers and check by actual multiplication. can you call these as identities?
