填空题:(a-b-c-d)(a+b-c+d)=[( )+( )][( )-( )]
填空题:(a-b-c-d)(a+b-c+d)=[( )+( )][( )-( )]
填空题:(a-b-c-d)(a+b-c+d)=[( )+( )][( )-( )]
=[(a-b)- (c-d )][(a-b )+(c-d)]
(a-b-c-d)(a+b-c+d)
=[( a-d)+(b+c )][(a-d )-(b+c )]
=(a-d)^2-(b+c)^2
(a-b-c-d)(a b-c d)=[( a-d) (b c )][(a-d)-(b c )]=(a-d)^2-(b c)^2
谢谢采的纳,手机打字好痛苦的
(a-b-c+d)(a-b+c-d)=[(a-b)- ( )][( )+(c-d)]填空题
A. B. C. D. 填空题,谢谢
填空题要过程已知数据a,a,b,c,d,b,c,c,且a
选择填空,选择A,B,C,D
填空题:(a-b-c-d)(a+b-c+d)=[( )+( )][( )-( )]
5数字数学填空题若a>b,c>d,则a(c-d)____b(c-d)
(a+b+c)^2 填空
A B C D
A B C D
(a+b)(c+d).
[a,b)×[c,d
a,b ,c ,d
a b c d
(a) (b) (c) (d)
A,B,C,D
A B C D
若a:b=b:c=c:d=1:2,则a:d=____(填空题)
计算:a/[(a-b)(b-c)]+b/[(b-c)(b-a)]+c/[(c-a)(c-d)]
