Question

Simply using algebraic identity
(x^2+y^2)(-x^2+y^2)

Answer 1

Answer:

( x^2 + y^2 )(—x^2 + y^2)

(Y^2 + x^2)(y^2 —x^2)

(A + B)(A-B) = a^2 - b^2

(y^2)^2 - (x^2)^2

= y^4 - x^4

Step-by-step explanation:

Answer 2

     

$\sf{According to} \ \ (a+b)(a-b)=a^2-b^2,$

$(x^2+y^2)(-x^2+y^2) \\ \\ (x^2+y^2)(-(x^2-y^2)) \\ \\ -(x^2+y^2)(x^2-y^2) \\ \\ -((x^2)^2-(y^2)^2) \\ \\ -(x^4-y^4) \\ \\ -x^4+y^4 \\ \\ y^4-x^4 \\ \\ \\ OR \\ \\ \\ (x^2+y^2)(-x^2+y^2) \\ \\ (y^2+x^2)(y^2-x^2) \\ \\ (y^2)^2-(x^2)^2 \\ \\ y^4-x^4$
