怎样化简(a+b)(a-b)+(4ab³-8a²b²)÷4ab
怎样化简(a+b)(a-b)+(4ab³-8a²b²)÷4ab

怎样化简(a+b)(a-b)+(4ab³-8a²b²)÷4ab
(a+b)(a-b)+(4ab³-8a²b²)÷4ab
=a^2-b^2+b^2-2ab
=a^2-2ab
=a(a-2b).

a²-b²+b²-2ab =a²-2ab

(a+b)(a-b)+(4ab³-8a²b²)÷4ab
=a^2-b^2+b^2-2ab
=a^2-2ab

(a+b)(a-b)+(4ab³-8a²b²)÷4ab
=a²-b²+b²-2ab
=a²-2ab
=a(a-2b) a,b不等于零

(a+b)(a-b)+(4ab³-8a²b²)÷4ab
=(a+b)(a-b)+4ab²(b-2a)÷4ab
=(a+b)(a-b)+b(b-2a)
=a²-b²+b²-2ab
=a²-2ab
=a(a-2b)

a平方-b平方+b平方-2ab=a(a-2b)
