Question

(a2-b2)(a2+b2)-(a2-b2)2

Answer 1

Answer:

Step-by-step explanation:

(a²-b²)(a²+b²)-(a²-b²)²

using identity: (a-b)(a+b)=a²-b²

[(a²)²-(b²)²]-(a²-b²)²

[a⁴-b⁴]-(a²-b²)²

using identity : (a-b)²=a²+b²-2ab

[a⁴-b⁴]-[(a²)²+(b²)²-2×a²×b²

a⁴-b⁴-[a⁴+b⁴-2a²b²]

a⁴-b⁴-a⁴-b⁴+2a²b²

2a²b²-2b⁴

2b²(a²-b²)
