3a^3b^2c-6a^2b^2c^2+3ab^2c^3
3a^3b^2c-6a^2b^2c^2+3ab^2c^3
3a^3b^2c-6a^2b^2c^2+3ab^2c^3
=3ab²c(a²-2ac+c²)
=3ab²c(a-c)²
(a-b+c/a+b-c)-(a-2b+3c/b-c+a)+(b-2c/c-a-b)
(a-b)(b-c)(c-a)/(b-a)(a-c)2(c-b)3
2a(a+b-c)-3b(a+b-c)+5c(c-a-b)
2a(b-c)+3(c-b)
化简|a-b|-2c-|c+b|+|3b| c
3a-c=4a+2b-c=a+b+c a:b:c
化简:7(a-b-c)-5(a+b-c)+3(a-b-c)+(a+b-2)
(a+b-c)^3*(c-b-a)^2*(a+b-c)^6 等于?)
已知:(a-b)(b-c)(c-a)/(a+b)(b+c)(c+a)=5/132,求a/(a+b)+b/(b+c)+c/(c+a)的值!(请尽快,我有急用,a/(a+b)+b/(b+c)+c/(c+a)=1/2[(a-b)/(a+b)+(b-c)/(b+c)+(c-a)/(c+a)]+3/2 (a-b)/(a+b)+(b-c)/(b+c)+(c-a)/(c+a) 没有错吧...
5a+{3b+[6c-2a-2(a-c)]}-[9a-(7b+c)]
5a-{-3b+[6c-2a-(a-c)]}-[9a-(7b+c)]
5a-{-3b+[6c-2a-(a-c)}-[9a-(7b+c)]
5a-{-3b+[6c-2a-(a-c)]}-[9a-(7b+c)]
计算:5a-{-3b+[6c-2a-(a-c)]}-[9a-(7b+c)]
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
[b/(a-b+c)]+[(2a+c)/(b-a-c)]-[(b-c)/(b-a-c)]
b/a-b+c+2a+c/b-a-c-b-c/b-c-a
数学题如图,化简|c|-|c-b|+|a-c|+|a+b|(2)化简:|c|-|c-b|(3)化简: |c|-|c-b|+|a-c|+|a+b|
