Answer:
Using Identity a²-b²=(a+b)(a-b)..
Step-by-step explanation:
=(2a+2b)(2a+2b)-(2a-2b) (2a-2b)
=(2a+2b)²-(2a-2b) ²
=(2a+2b+2a+2b)(2a+2b-2a+2b)
=(4a+4b)×0
=0

Answer:
(a²+b²)(a²+b²)-(a²-b²)(a²-b²)
=a²(a²+b²)+b²(a²+b²)-[(a²)(a²-b²)+(-b²)(a²-b²)]
=a⁴+a²b²+a²b²+b⁴-(a⁴-a²b²-a²b²+b⁴)
=a⁴+2a²b²+b⁴-a⁴+a²b²+a²b²-b⁴
=4a²b².
