Question

If a+b+c=0 then a^2÷bc+b^2÷ca+c^2÷ab=?​

Answer 1

Answer:

0

Step-by-step explanation:

$\frac{ {a}^{2} }{bc} + \frac{ {b}^{2} }{ca} + \frac{ {c}^{2} }{ab} = ?$

$= \frac{ {a}^{3} + {b}^{3} + {c}^{3} }{abc}$

as we know that

a³+b³+c³ = (a+b+c)(a²+b²+c²-ab-bc-ca)

put a+b+c=0

a³+b³+c³=0
