(-2ab^2)^2·(3a^2b-2ab-4b^3)(-2ab^2)^2·(3a^2b-2ab-4b^3)(-2ab^2)^2·(3a^2b-2ab-4b^3)原式=(4a²b^4)(3a
(-2ab^2)^2·(3a^2b-2ab-4b^3)
(-2ab^2)^2·(3a^2b-2ab-4b^3)
(-2ab^2)^2·(3a^2b-2ab-4b^3)
原式=(4a²b^4)(3a²b-2ab-4b³)
=12a^4n^5-8a³b^5-16a²b^7
(a-b)^3+2ab(a-b)
a+b/2ab
2AB/A+B
a+b/2ab
ab/a+b=3 a-2ab+b/2a-3ab+2b?
3(-ab+2a)-(3a-b)
3(-ab+2a)-(3a-b)
因式分解:a×a×a-2a×a×b+ab×b
3ab·(a²b-ab²+ab)-ab²(2a²-3ab+2a)
(ab(a^-2ab)-a^2b(a-3b))÷(3a^b)
-2ab乘以(-a^+6a^b-3a+b)
18ab(a-b)^2-12a(b-a)^3
a^3-ab^2 =a (a^2 -b^2) =a(a+b)(a-b)
(a-b)平方-2ab(b-a)
a^2b-ab+2ab^2-5a^b-4ab+3ab^2化简快
a+3b/a²-b²·a²+2ab+b²/(a+3b)(a-b)
3(-2ab+3a)-(2a-b)+6ab
3(-ab+2a)-(3a-b)+2ab
