Question

(x^2-xy+y^2)(x^2+xy+y^2)​

Answer 1

Step-by-step explanation:

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

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

= x^4+x^3y+x^2y^2-x^3y-x^2y^2-xy^3+x^2y^2+xy^3+y^4

=x^4+y^4+x^2y^2

Answer 2

Explanation :

( x² - xy + y² ) ( x² + xy + y² )

Multiply the numbers in the first bracket with second bracket.

Now, x⁴ - x²y² + y⁴

This is your required answer.
