(a²+2ab+b²)⁻¹ . (2a-b)⁻² ₋ (a²+2ab+b²)⁻¹ * (4a²-4ab+b²)³ ₋
______________________________________________________
(a+b)⁴ ⁺ (4a²-4ab+b²)³ ⁻ (a+b)⁴ * (2a-b)⁻² ⁻


=[(-a + (-2ab) + (-b²))*(4a⁶-4ab³+b⁶)] : [(a⁴+b⁴)*(2a-b)]=
= [(-a-2ab-b²)*(4a⁶-4ab³+b⁶)] : [2a⁵-b⁵]=
= [-a⁷+8ab⁴-b⁸]:[2a⁵-b⁵]= [a⁷+8ab⁴-b³] : [2a⁵]

ale nie jestem pewna
