$( { {a}^{2} - {b}^{2}) }^{2} \\ {a}^{4} - {b}^{4} \\ ( {a}^{2} + {b}^{2} )(a + b)(a - b)$

Answer 2

Answer:

a⁴-2a²b²+b⁴

Step-by-step explanation:

let us consider a²as x and b² as y, then we are getting (x-y)² instead of given figure , then by applying the formula x²-2xy + b², and lastly puttiing the value of x and y we get (a²)²-2a²b²+(b²)²= a⁴+2a²b²+b⁴
