(4a+3b)(3a+b)-(a+b)
计算:3a+4b/a-b+3b/b-a-4a/a-b
3a/a-4b +a+b/4b-a -7b/a-4b
1.(a-b)^2(b-a)^3(a-b)^-4
(3a-6b)/(a+b) - (5a-6b)/(a-b) - (4a-5b)/(a+b) - (7a-8b)/(a-b
(3a-6b/a+b)-(5a-6b/a-b)-(4a-5b/a+b)-(7a-8b/b-a)
[a+b][a-b]+3a
4(b-a)(a+b)-(2a-3b)(3a-2b)怎么计算
(a+2b)(2a+4b)(3a+6b)(4a+8b)
a-4b分之3a+4b-a分之a+b-a-4b分之7b=
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
2a-[-3b+4a-(3a-b)
3a(a-b)-5b(a-b)
