" 20.If "a+b+c=0" then "((a^(2))/(bc)+(b^(2))/(ca)+(c^(2))/(ab))=?

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

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

If a + b + c = 0, then x^((a^(2))/(bc)), x^((b^(2))/(ca)) , x((c^(2))/(ab)) equals :

If a+b+c=0, the value of (a^(2))/(bc)+(b^(2))/(ca)+(c^(2))/(ab) is 3abc(b)(1)/(3)(c)1(d)3

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

If a,b,c are non-zero real numbers and a+b+c=0, then the value of (a^(2))/(bc)+(b^(2))/(ca)+(c^(2))/(ab) is (A)0(B)2(D)4(C)3
