If `a b+b c+c a=0` , then what is the value of `(1/(a^2-b c)+1/(b^2-c a)+1/(c^2-a b))` ? (a) 0 (b) 1 (c) 3 (d) `a+b+c`

If a+b+c=0 , find the value of (a^2)/((a^2-b c))+(b^2)/((b^2-c a))+(c^2)/((c^2-a b)) (a) 0 (b) 1 (c) 2 (d) 4

If a+b+c =0, then the value of frac(a^2 +b^2+c^2) (a^2 - bc) is (A) 0 (B) 1 (C) 2 (D) 3

If a b c=0 , then find the value of {(x^a)^b}^c (a)1 (b) a (c)b (d) c

If a+b=2c, then the value of (a)/(a-c)+(b)/(b-c) is (1)/(2)(b)1(c)2(d)3

If a + b + c = 0 then the value of (1)/((a + b) ( b + c)) + (1)/(( a + c) ( b + a))+ (1)/( ( c + a) ( c + b)) is

if a^(2) = b + c, b^(2) = a + c, c^(2) = b + a then what will be the value of (1)/ ( a + 1) + (1)/( b + 1) + (1)/( c + 1)

If a ^(2)= b + c, b ^(2) = a + c, c ^(2) = b + , then what will be the value of (1)/(a + 1) + (1)/(b +1) + (1)/(c +1) = ?
