已知实数a.b.c满足a-b的绝对值=-2根号2b+c-(c-2分之1)的平方,求a(b+c)的值
<p>问题：已知实数a.b.c满足a-b的绝对值=-2根号2b+c-(c-2分之1)的平方,求a(b+c)的值<p>答案：↓↓↓<p class="nav-title mt10" style="border-top:1px solid #ccc;padding-top: 10px;">胡志才的回答：<div class="content-b">网友采纳 ∵实数a,b,c满足a-b的绝对值+根号(2a+c)+c-c+1/4=0∴a-b=02a+c=0c-c+1/4=(c-1/2)=0∴c=1/2a=-1/4b=1/4∴a（b+c)=-3/16
