Answer 1

Step-by-step explanation:

= a²/bc + b²/ac + c²/ab

= (a³+b³+c³)/abc

we know that,

a³+b³+c³ = (a+b+c)(a²+b²+c²-ab-bc-ca) + 3abc

=> ( (a+b+c)(a²+b²+c²-ab-bc-ca) + 3abc ) / (abc)

=> ( 0 + 3abc)/abc

=> 3

Answer 2

$\huge\boxed {Answer}$

Given :-

a + b + c = 0

We know that

if (a + b + c) = 0

then (a³ + b³ + c³) = 3abc

Explanation :-

a²/bc + b²/ca + c²/ab

=> (a³ + b³ + c³)/abc

=> (3abc)/abc

=> 3
