<p>问题：【若a+b+c=0,求(bc分之a^2)+（ac分之b^2)+（ab分之c^2)的值】<p>答案：↓↓↓<p class="nav-title mt10" style="border-top:1px solid #ccc;padding-top: 10px;">巴文厂的回答：<div class="content-b">网友采纳 a^2/(bc)＝(b＋c)^2/(bc)＝b/c＋c/b＋2b^2/(ac)＝(a＋c)^2/(ac)＝a/c＋c/a＋2c^2/(ab)＝(b＋a)^2/(ab)＝b/a＋a/b＋2三式相加得：原式＝(b/c＋a/c)＋(c/b＋a/b)＋(c/a＋b/a)＋6＝(b＋a)/c＋(c＋a)/b＋(c＋b)/a＋6＝(...
