[(b^4)/(-2ab+a^2+b^2)]*[(a^3+2b^2-2a^2-2a^2b)/(b^3)]/[(b^2-a^2)/(ab+b^2)]
=[b^4/(b-a)^2]*[(a^3+2b^2-2a^2-2a^2b)/b^3]/[(b-a)(b+a)/b/(a+b)]
=[b^4/b^3]*[(a^3+2b^2-2a^2-2a^2b)/(b-a)^2]*[b/(b-a)]
=b^2/(b-a)^3*(a^3+2b^2-2a^2-2a^2b)

因式分解a^+b^+2a^b+2ab^+a^+b^+3ab+a+b
若a/b=2 则a*a-ab+b*b/a*a+b*b等于?
A=B+B+B+B+B+B+B+B+B+B+B+B+B+B+B A-B×3=C C+2×7+2=1
计算:((a+b)(a-b)-(a-b)^2+2b(a-b))/4(a-b)
(a-b)(a^2+ab+b) 化简
1.(a-b)^2(b-a)^3(a-b)^-4
已知3a*a+ab-2b*b=0(a不等于0,b不等于0),求a/b-b/a-(a*a+b*b)/ab的值.
a+b/2ab
