计算:(4a-b)^2-[8a*(a-b)-(3a-b)*(3a+b)]
(a+2b)(2a+4b)(3a+6b)(4a+8b)
若a-b=4,3a+2b=6,3a(a-b)+2b(a-b)=( ).
(3a+4b)(7a-8b)+(11a+2b)(8a-7a)
2(a+3b)²-8(a+b)(a-b)-(a+3b)(a-b)
2(a+b)-[4(a+b)-3(a+b)]一[5(a-b)+(a-b)]过程
初二分式的加减法2a-b-c/(a-b)(a-c)+ 2b-c-a/(b-c)(b-a)+ 2c-b-a/(c-b)(c-a)3a-6b/a+b- 5a-6b/a-b- 4a-5b/a+b+ 7a-8b/b-a注:有空格的地方是下一个分式
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
若(4a+3b-17)^2+|8 a-b+1|=,则a= ,b=
若a-b/a+b=4,求5a-b/a+b- a+b/2(a-b)
若a-b/a+b=4,求代数式5(a-b)/a+b-a+b/2(a-b)
(3a-6b)/(a+b) - (5a-6b)/(a-b) - (4a-5b)/(a+b) - (7a-8b)/(a-b) 快
(3a-6b/a+b)-(5a-6b/a-b)-(4a-5b/a+b)-(7a-8b/b-a)
[2(a-b)^2+4(a-b)^4+8a(a-b)^3]/2(a-b)^2
已知(a-2b)/(a+2b)=4,求代数式3(a-2b)/4(a+2b)+(4a+8b)/(a-2b)的值
若a-b/a+b=4 则代数式2a﹣2b/a+b-4a+4b/3a-3b=
(a-2b)/(a+2b)=3,求(a+2b)/(a-2b)+(3a-6b)/(4a+8b)的解,
