Question

Verify: (i) x3 + y2 = (x + y) (x2 - xy + y2) (ii) x3 - y3 = (x - y) (x2 + xy +
h of the following:
(ii) 64m3 – 343n3​

Answer 1

1). x3+y3=x(x2-xy+y2) +y(x2-xy+y2)

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

x3+y3= x3+y3 bacha kyoki -x2y Se +x2y cut. ho gaya or +xy2 se -xy2 cut gay's isliye first ka answer x3+y3=x3+y3 ays
