a^2+6a(b+c)+9(b+c)^2 因式分解
a^2+6a(b+c)+9(b+c)^2 因式分解
a^2+6a(b+c)+9(b+c)^2 因式分解
a^2+6a(b+c)+9(b+c)^2
把b+c看为整体,利用完全平方公式
=【a+3(b+c)】^2
=(a+3b+3c)^2
a^2+6a(b+c)+9(b+c)^2
=a^2+6a(b+c)+[3(b+c)]^2
= (a+3b+3c)^2
[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
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)]
(a-b+c/a+b-c)-(a-2b+3c/b-c+a)+(b-2c/c-a-b)
化简a(a+b)(a+c)/(a-b)(a-c) +2b^2(c-a)/(b-c)(b-a) +2c^2(a+b)/(c-a)(c-b)
化简a(a+b)(a+c)/(a-b)(a-c) +2b^2(c-a)/(b-c)(b-a) +2c^2(a+b)/(c-a)(c-b)
因式分解(b-c)(b+c)^2+(c-a)(c+a)^2+(a-b)(a+b)^2
(a-b)(b-c)(c-a)^2/(b-a)^2(a-c)(c-b)约分
(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)
化简:2a-b-c/(a-b)(a-c) + 2b-a-c/(b-c)(b-a) + 2c-a-b/(c-b)(c-a)
化简:(2a-b-c)/(a-b)(a-c)+(2b-c-a)/(b-c)(b-a)+(2c-a-b)/(c-a)(c-b)
化简:(2a-b-c)/(a-b)(a-c)+(2b-c-a)/(b-c)(b-a)+(2c-a-b)/(c-a)(c-b)
化简(2a-b-c)/(a+b)(a-c)+(2b-c-a)/(b-c)(b-a)+(2c-a-b)/(c-b)(c-a)
