(1)化简:5a+(4b-c)-3(a+3b-2c)
(1)化简:5a+(4b-c)-3(a+3b-2c)

(1)化简:5a+(4b-c)-3(a+3b-2c)
5a+(4b-c)-3(a+3b-2c)
= 5a+4b-c-3a-9b+6c
= 2a-5b+5c

化简:5(a-2b+c)-4(-a+b-c)+4(3a-2b) (1)化简:5a+(4b-c)-3(a+3b-2c) (1)化简:5a+(4b-c)-3(a+3b-2c) 数学化简题有点难不过做化简题 希望你们帮帮忙 化简1)(a+b)(a+b)-(a-b)(a-b) 2) (3x-2y)(3x-2y)-(3x+2y)(3x+2y)3) (a+b)(a-b)-(b+a)(b-a)4) (3a+2b)(3a-2b)+(3a-2b)(3a-2b)5)(a+b+c)(a+b+c)-(a-b-c)(a-b-c)6) (2a+b-3c)(2a+b-3c 若|a|=3|b|=1|c|=5且|a+b|=a+b,|a+c|=-(a+c)求a+b+c的值 因式分解(a+b)(b+c)(c+a)+abc1.(a+b)(b+c)(c+a)+abc2.(c+a-b)(b+c-a)(a+b-c)+a(a-b+c)(a+b-c)+b(a+b-c)(-a+b+c)+c(-a+b+c)(a-b+c)3.1-12x^2y^2+48x^4y^4-64x^6y^64.m^5+m+1 (1)代数式a-b+c的相反数是( )A.a-b+c B.b-a+c C.c-a+b D.b-a-c(2)已知a+b=5,ab=-3,求代数式(2a-3b-2ab)-(a-4b-ab)的值(3)一条数轴 c a与b互为相反数,a与c互为倒数(a≠0,±1),化简(a^3-b/a+c)-(a+b^3/b+c) 5a-{-3b+[6c-2a-(a-c)]}-[9a-(7b+c)] ( )1 A.great B.cake C.easy ( )2 A.May B.Tuesday C.today ( )3 A.doctor B.door C.floor( )4 A.purple B.bird C.daughter ( )5 A.balloon B.food C.good ( )1 A.great B.cake C.easy ( )2 A.May B.Tuesday C.today ( )3 A.doctor B.door C.floor( )4 A.purple B.bird C.daughter ( )5 A.balloon B.food C.good 化简2a-[3a-5a-(2a-7b)]等于( ).A、-7a+10b B、5a+4b C、-a-4b D、9a-10b If a-b+c>0,then ( )A.b(a+c)>b^2B.(a+c)^2>b(a+c)C.1/a+cb^5 化简(2a-b-c)/(a+b)(a-c)+(2b-c-a)/(b-c)(b-a)+(2c-a-b)/(c-b)(c-a) 化简【(2a-b-c)/ (a-b)(a-c)】+【(2b-a-c) / (b-c)(b-a) 】+【(2c-a-b) / (c-b)(c-a)】 C语言的几道题帮我解一下.写出下面各逻辑表达的值设a=3 ,b=5 ,c=5(1)a+b>c &&b==c(2)a‖b+c &&b-c(3)!(a>b) && c‖1(4)!(x=a) &&(y=b)&&0(5)!(a+b)+c-1&&b+c/2 化简 3a-{2c-【6a-(c-b)+c+(a+8b-9c)】} (3a的平方-ab+1)-(4a的平方+6ab+7)3a-{2c-【6a-(c-b)+c+(a+8b-9c)】}(3a的平方-ab+1)-(4a的平方+6ab+7) (a+b)+5(c-d)化简(a+b)-3(c-d)-(a-b)-(c-d)
