立方差公式 姐姐
化简【3A方-(A+B)(B-A)】【4(-B-A)(B-A)+5B方】
化简 (a+b)²+2a(a-1/2b)-3(a-b)(a+b)
计算:(4a-b)^2-[8a*(a-b)-(3a-b)*(3a+b)]
1/(a-b)-1/(a+b)-(2b)/(a^2+b^2)-(4b^3)/(a^4+b^4)+(8b^7)/(b^8-a^8)快
1/a-b-1/a+b-2b/a^2+b^2-4b^3/a^4+b^4+8b^7/b^2-a^2
(3a-6b)/(a+b) - (5a-6b)/(a-b) - (4a-5b)/(a+b) - (7a-8b)/(a-b) 快

化简;(a+b)^2-2分之3(a+b)-4分之1(a+b)^2+(﹣2)^3(a+b)
已知A=-1/2a^2b,B=4ab^3-8a^2b^2,试用a,b表示整式2A^2B(A-B)+A^2B(2B-A)
因式分解:1、a*a*a*a+2a*a*a*b+3a*a*b*b+2a*b*b*b+b2、(a+1)(a+3)(a+4)(a+6)-280
