已知实数a,b,c满足1/2ㄧa-bㄧ+(根号下2b+c)+c2-c+1/4,求a(b+c)的值.
已知实数a,b,c满足1/2ㄧa-bㄧ+(根号下2b+c)+c2-c+1/4,求a(b+c)的值.

已知实数a,b,c满足1/2ㄧa-bㄧ+(根号下2b+c)+c2-c+1/4,求a(b+c)的值.
1/2(a-b) 根号下(2b c) c^2-c 1/4=0
a-b=0
2b c=0
c-1/2=0
c=1/2
b=-1/4
a=1/4
a(b c)=-1/16

已知一个,,C相遇| AB | +√(2B + C)+ C ^ 2-C +1 / 4 = 0
即| AB | +√(2B + C)+(C-1 / 2)^ 2 = 0
三都是非负的,加起来等于0,那么只需要
| AB | = 0 2B + C = 0°C-1/2 = 0 BR /> = -1 / 4 = -1 / 4的C = 1/2
所以A + B + C =(-1 / 4)+(-1 / 4)+(1 / 2)= 0
