( (x-a)^{3}+(x-b)^{3}+(x-c)^{3} ) ( x=frac{a+b+c}{3} ) we know ( k ) [ text { if } quad p+q+r=0 ] here ( p=x-a ) [ begin{array}{l} begin{aligned} q &=x-b r &=x-c p+q+r &=3 x-a-b-c=0 s 0 & quad(x-a)^{3}+(x-b)^{3}+(x-c)^{3} &=3(x-a)(x-b)(x-r) &=3left(frac{b+c-2 a}{3}right)left(frac{a+c-2 b}{s}right) frac{a+b-2 c}{3} end{aligned} end{array} ]
