Simplify (x+y)(x-y)+x^2+y^2

Answer»

y)(x² - XY + y²)⇒ X(x² - xy + y²) + y(x² - xy + y²)⇒ x³ -x²y + xy² +x²y -xy² + y³⇒ x³ + y³ - x²y + x²y - xy² + xy²⇒ x³ + y³    (This is actually a identity,you can use while solving problems).,._____________________________________________________________                                       Hope it Helps !!⇒ Mark as BRAINLIEST (if POSSIBLE)
