2ab(-3a)+(-2b)*4a^2
2ab(-3a)+(-2b)*4a^2
2ab(-3a)+(-2b)*4a^2
2ab(-3a)+(-2b)*4a^2
=-6a^2b-8a^2b
=-14a^2b
¡à3a -[a b-(3ab-a b)-4a ]-2ab =3a -a b+3ab-a b+4a -2ab =7a -2a b+ab =7*(-2) -2*(-2) *(-3)+(-2)*(-3) =48+24+
=-6ba^2-8ba^2
=-14ba^2
a^2b-ab+2ab^2-5a^b-4ab+3ab^2化简快
(a-b)^3+2ab(a-b)
1/4a^2b^2{3ab(a+b)-5a(ab-b^2)}=?
(a-b)(a^5+a^4b+a^3b^2+ab^4+b^5)bggg
-2ab(3a^2-2ab-4b^2) (2b-a)b-（2a-b）a-2ab(3a^2-2ab-4b^2)(2b-a)b-（2a-b）a
-4a^3b+6a^2b-2ab
2a²b(a-b)+ab(a-b)²+4ab²(a-b)
5ab^2-{2a^b-[3ab^2-(4ab^2-2a^2b)]}
a+b/2ab
2AB/A+B
a+b/2ab
化简[(a-b)/(a+2b)]/[(a^2-b^2)/(a^2+4ab+b^2)]-(3a^2-4ab)/(a^2+ab)
求化简 (a-b)/(a+2b)除以(a^2-b^2)/(a^2+4ab+b^2)-(3a^2-4ab)/(a^2+ab)
ab/a+b=3 a-2ab+b/2a-3ab+2b?
计算(a^3-4a^2b-a+4ab^2)/a(a-2b+1)
{ab-[3a²b-(4a²b+1/2ab)]-4a²b}+3a²b
计算2A(A^2 -AB+B^2)-3AB(4A-2B)
3(-ab+2a)-(3a-b)
