Question

VERIFY the POLYNOMIAL IDENTITY :-
​

Answer 1

Answer:

x^3 - y^3 = x^3 - y^3 - 3xy (x-y).

Ur identity is wrong.

hope it helps u. plz mark as brain list answer plz

Answer 2

Answer:

(x-y)^3=x^3 -y^3 +3xy(x-y)

(x-y)^3 -3xy(x-y)=x^3-y^3

(x-y)[(x-y)^2-3xy]=x^3-y^3

(x-y)(x^2+y^2-2xy-3xt)=x^3-y^3

(x-y)(x^2+y^2+x-y)=x^3-y^3
