Question

Simplify :-
(step by step)

(i) (x²-xy +y²) (x²+xy+y)²
(ii)(x+y)² + (x-y)²
(iii)(x+y)² - (x-y)²

plz............. it's urgent
no spam plz..........
​

Answer 1

(iii) (a + b) ² = a ² + 2ab + b ²

(a - b) ² = a ² - 2ab + b ²

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

(x + y) ² - ( x - y) ² =

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

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

x ² + 2xy + y ² - x ² + 2xy - y ² =x ² - x ² + 2xy + 2xy + y ² - y ² =

0 + 4xy + 0 = 4xy

question 2 and 3 are same
