(ab+2ab^2-3a^2b)/(ab)七下谢谢(ab+2ab^2-3a^2b)/(ab)七下谢谢(ab+2ab^2-3a^2b)/(ab)七下谢谢(ab+2ab^2-3a^2b)/(ab)=ab(
(ab+2ab^2-3a^2b)/(ab)七下 谢谢
(ab+2ab^2-3a^2b)/(ab)
七下 谢谢
(ab+2ab^2-3a^2b)/(ab)七下 谢谢
(ab+2ab^2-3a^2b)/(ab)
=ab(1+2b-3a)/(ab)
=1+2b-3a
=ab(1+2b-3a)/(ab)
=1+2b-3a
1+2b-3a
a^2-3ab+b^2/ab=( )/ab-3
a^2-3ab+b^2/ab=( )/ab -3
a^2b-ab+2ab^2-5a^b-4ab+3ab^2化简快
计算:2ab[(2ab)²-3b(ab+a²b)-ab²]
3ab{(-2ab)平方-3b(ab-a平方b)+ab平方}算出来多少Rt
a+b/2ab
2AB/A+B
a+b/2ab
求3ab(a^b+ab^2-ab)-ab^2(2a^2+3ab-2a)的值
3ab(a²b-ab²-ab)-ab²(2a²-3ab+2a)
3ab(a²b-ab²-ab)-ab²(2a²-3ab+2a)
3ab·(a²b-ab²+ab)-ab²(2a²-3ab+2a)
3ab(a²b-ab²-ab)-ab²(2a²-3ab+2a)
已知a+b=3,ab=2 求 ab+2ab+ab 的值
合并同类项5a²b-3ab-4ab²+7ab-2ab²
计算3ab(2ab^2-ab-b^2)-6ab(a^2-2ab-b^2)
ab/a+b=3 a-2ab+b/2a-3ab+2b?
-ab(a^2b^5-ab^3-b)
