2个回答
{ab-[3a^2b-(4a^2b+1/2ab)]-4a^2b}+3a^2b
=ab-3a²b+4a²b+ab/2+4a²b+3a²b
=3ab/2+8a²

若a-b=4,ab=1,求(-2ab+2a+3b)-(3ab+2b-2a)-(a+4b+ab)
-3/4ab+2/3a^2b+ab-a^2b-1/2ab-5/3a^2b
若a-b=4,ab=1,求(-2ab+2a+3b)-(3ab+2b-2a)-(a+4b+ab)的值
(1)-3a-(-2a+2b-c)(2)4a²+3b²+2ab-4ab-4b² (3)3x
2/3ab+3/4a^2b+ab+(-3/4a^2b)-1
1/4a^2b^2(3ab(a+b)-5a(ab-b^2))
-2ab(3a^2-2ab-4b^2) (2b-a)b-(2a-b)a
3a²b-[2a²b-﹙2ab-a²b﹚-4a²]-ab其中a=3.b=-2
1/2a^2b+(5a^2b-ab^2)-(-1/4a^2b+3a)-(3ab^2-6)
已知A=2A^2+3ab-b^2,B=-1/2ab,C=3/2a^3b^3-1/4a^2b^4.求2A乘B^2-C
