回答1:

(a加b)(a减b)加(4ab的立方-8a的平方b的平方)除以4ab
=a²-b²+4ab(b²-2ab)÷4ab
=a²-b²+b²-2ab
=a²-2ab

回答2:

(a+b)(a-b)+(4ab³-8a²b²)/4ab
=(a²-b²)+[4ab(b²-2ab)/4ab]
=(a²-b²)+(b²-2ab)
=(a²-b²)+(b²-2ab)
=a²-b²+b²-2ab
=a²-2ab
=a(a-2b)

回答3:

(a加b)(a减b)加(4ab的立方-8a的平方b的平方)除以4ab
=a²-b²+4ab(b²-2ab)÷4ab
=a²-b²+b²-2ab
=a²-2ab
