Answer 2

Answer:

(x²-y²)²

Step-by-step explanation:

Using basic mathematics rule,

While opening the brackets,

=>(x-y)²x(x+y)²

=>( x²+y²-2xy)(x²+y²+2xy)

Let,

x²+y²=A

then the equation is,

=>(A-2xy)(A+2xy)

====>>> This is of the form,

(a+b)(a-b)

=> a²-b²

=> A² -4x²y²

since, A= x²+y²

so,

=>(x²+y²)²-4x²y²

=> x^4+y^4+x²2y²-4x²y²

=> x^4+y^4-2x²y²

=> and as this satisfy above equations,

we get,

=> (x²-y²)²
