Question

If a+b+c = 0 then a²/bc + b²/ca + c²/ab ​

Answer 1

Step-by-step explanation:

$\large \pink{ \underline{given \: a + b + c = 0}} \\ \large \green{ \frac{ {a}^{2} }{bc} + \frac{ {b}^{2} }{ca} + \frac{ {c}^{2} }{ab} } \\ \large \green{ = \frac{ {a}^{3} + {b}^{3} + {c}^{3} }{abc} } \\ \large \green{ = \frac{3abc}{abc} } \\ \large \green{ = 3}$
