$a + b + c = 0$
then find the value of
$a {}^{2} \div bc + b {}^{2} \div ac + c {}^{2} \div ab$

Answer 1

3 is the answer
use property

Answer 2

Answer:3

Step-by-step explanation

=a^2/bc +b^2/ac+c^2/ab

Take LCM of bc ac ab = abc

=(a^3+b^3+c^3)÷abc

=(a^3+b^3+c^3-3abc+3abc)÷abc

=(a+b+c)(a^2+b^2+c^2-ab-bc-ca)+3abc÷abc

=0+3abc÷abc

=3abc÷abc

=3

Hope this helps.
