take t to the left your equation will look like
a+b=-c
cube both side
a3+b3+3a2b+3ab2=-c3
now divide it by abc

roushan12: when a+b+c=0 then a^3+b^3+c^3=3abc a^2/bc +b^2/ca +c^2/ab=(a^3+b^3+c^3)/abc=3abc/abc=3

roushan12: are u understand

saurabh198: noo

roushan12: a^3+b^3+c^3-3abc=(a+b+c)(a^2+b^2+c^2-ab-bc-ca) given that a+b+c=0 then a^3+b^3+c^3-3abc=0 a^3+b^3+c^3=3abc
