Question

Please solve it in a different sheet!!

Answer 1

Can be proved this way

Answer 2

$Given: \frac{a^2}{bc} + \frac{b^2}{ca} + \frac{c^2}{ab}$

LCM = abc.

$\frac{a^2 * a + b^2 * b + c^2 * c}{abc}$

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

We know that if a + b + c = 0, Then a^3 + b^3 + c^3 = 3abc.

$\frac{3abc}{abc}$

3.


Hope this helps!
