(3a+4b)(7a-8b)+(11a+2b)(8b-7a)
=(3a+4b)(7a-8b)-(11a+2b)(7a-8b)
=(7a-8b)(3a+4b-11a-2b)
=(7a-8b)(2b-8a)
(3a+4b)(7a-8b)+(11a+2b)(8a-7a)

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
5(a*a*b-3*a*a*b)-2*(a*a*b-7*a*b*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
已知A=5a-3b,B=-6a+4b,则A-B等于 A.-a+b,B=11a+b C.11a-7b D -a-7b
若7a-8b=5.求(3a-4b)(7a-8b)-(11a-12b)(8b-7a)的值
7a-8b=5,求(3a-4b)(7a-8b)-(11a-12b)(8b-7a)
把多项式(3a-4b)(7a-8b)-(11a-12b)(7a-8b)因式分解的结果是A.8(7a-8b)(a-b)B.2(7a-8b)²C.8(7a-8b)(b-a)D.-2(7a-8b)
