Question

/ Page . Add: (x+y)(xsquare-xy+y square)to(x-y)(x square -xy-y square​

Answer 1

Sidharth Bhai and draw the syllabus of science in the world and the other one is not joining

Answer 2

(x + y) (x² - xy + y²) + (x - y) (x² - xy - y²)

= x (x² - xy + y²) + y (x² - xy + y²) + x (x² - xy - y²) - y (x² - xy - y²)

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

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

= 2x³ - 2x²y + 2y³

= 2(x³ - x²y + y³)
