are yaar isko simplify kardo.
x×x = x^2
y×y = y^2
so it becomes
(x^2 - y^2)(x^2+y^2)
Now use difference of squares I.e.
(a+b)(a -b) =(a^2 -b^2). .....1
Treat x^2 as a and -y^2 as -b
Now fit it in 1,
(( x^2)^2 - (y^2)^2)
= x^4 -y^4
x×x = x^2
y×y = y^2
so it becomes
(x^2 - y^2)(x^2+y^2)
Now use difference of squares I.e.
(a+b)(a -b) =(a^2 -b^2). .....1
Treat x^2 as a and -y^2 as -b
Now fit it in 1,
(( x^2)^2 - (y^2)^2)
= x^4 -y^4
