If a+b+c=0, then (a^(2))/(bc)+(b^(2))/(ca)+(c^(2))/(ab)=0 (b) 1(c)-1(d)3

Ifa+b+c=0, findthevalue ((b+c)^(2))/(bc)+((c+a)^(2))/(ca)+((a+b)^(2))/(ab)

If a+b+c=0, then the value of ((a+b)^(2))/(ab)+((b+c)^(2))/(bc)+((c+a)^(2))/(ca) is

|(a,b,c),(a^(2),b^(2),c^(2)),(bc,ca,ab)|=

If a , b , c are all non-zero and a+b+c=0 , then (a^(2))/(bc)+(b^(2))/(ca)+(c^(2))/(ab)= ? .

If ab + bc + ca = 0, then what is the value of (a^(2))/(a^(2) - bc) + (b^(2))/(b^(2)-ca) + (c^(2))/(c^(2) - ab) ?

If a,b,c are all non-zero and a+b+c=0 prove that (a^(2))/(bc)+(b^(2))/(ca)+(c^(2))/(ab)=3
