(-2a)^2(1/2ab+b^2)+(3a^2-2ab^2)(-1/2a)化简(-2a)^2(1/2ab+b^2)+(3a^2-2ab^2)(-1/2a)化简(-2a)^2(1/2ab+b^2)+(
(-2a)^2(1/2ab+b^2)+(3a^2-2ab^2)(-1/2a)化简
(-2a)^2(1/2ab+b^2)+(3a^2-2ab^2)(-1/2a)
化简
(-2a)^2(1/2ab+b^2)+(3a^2-2ab^2)(-1/2a)化简
答:
(-2a)^2(1/2ab+b^2)+(3a^2-2ab^2)(-1/2a)
=4a^2(1/2ab+b^2)-1/2a^2(3a-2b^2)
=a^2(2ab+4b^2-3/2a+b^2)
=a^2(2ab+5b^2-3/2a)
=2a^3b+5(ab)^2-3/2a^3
(a+b-2ab)(a+b-2)+(1-ab)^2
a+b/2ab
2AB/A+B
a+b/2ab
急……ab/(a+b-1)(a+b) + ab/(a+b)(a+b+1) + ab(a+b+1)(a+b+2) + …… + ab/(a+b+98)(a+b+99) + ab/(a+b+99)(a+b+100)
计算ab/(a+b-1)(a+b)+ab/(a+b)(a+b+1)+ab/(a+b+1)(a+b+2)+.+ab/(a+b+98)(a+b+99)+ab/(a+b+99)(a+b+100)
ab^3+b^2+b-a+1
(a-b+ab-a^2/a+b)乘以[a+1/a-b乘以(1+a/b)]
(a^2b-ab-a+1)/(ab^2+3ab-b-3)÷(a^2+a_2)/(b^2+b-6)
b/(a^2-ab)+c/(b^2-ab)+(a+b^2)/(a^2b-ab^2)
(a-b)平方-2ab(b-a)
(a-b)^3+2ab(a-b)
因式分解(a+b-2ab)(a+b-2)+(1-ab)(1-ab)
ab+a+b+1-2ab=2ab,则a+b的值为?
1/4a^2b^2{3ab(a+b)-5a(ab-b^2)}=?
因式分解ab(ab+1)^2-ab(a+b)-a-b+1 急求!
求证:A/(AB+B^2)-B/(AB+A^2)=1/B-1/A
[(a^2-2ab)/-ab+b^2]/[(a/a+b)/(2ab/2b-a)]
