Question

( a+b+c=0 quad b+c=(-a) quad a+c=(-b) quad a+b=(-c) )
( frac{(b+c)^{2}}{b c}+frac{(c+a)^{2}+b^{3}+c^{3}=3 a b c}{a}+frac{(a+b)^{2}}{a b} )
( frac{a^{3}+b^{3}+c^{3}}{frac{a b^{2}}{b c}+frac{3 a b c}{a b c}}=3( ) fan
( frac{a b^{2} b^{2}}{a b^{2}}+frac{(-c)^{2}}{a b} )

# O (c + a,(a+b) ifa+b+c= 0, then find the value of b+c) bcca ab
