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
1.（a-b)^2（b-a)^3(a-b)^-4
3a+2b用a+b,a-b表示
因式分解(a-b)^2*(a+b)-(a-b)^3
[（a+2b)(a-2b)-(2a-b)²+(3a-b)(3a-5b)]÷2a
a-b\a+b=1\2时,求代数式a+b\3(a-b) - a-b\2(a+b)
(-a+2b)+(2a-3b)
(a-2b)(a+3b)等于
b-a+3(a-b)^2 因式分解
化简 |a+b|-|3a-2b|
已知2a-b+1的绝对值+(3a+3/2b)^=0,求(b^/a+b)÷{[(b/a-b)+1][a-(a^/a+b)]
化简 (a+b)²+2a(a-1/2b)-3(a-b)(a+b)
