Question

what will be.....a^3+b^3+c^3 (identity)

Answer 1

Answer:

Im not sure but i think your question is wrong, it must be (a + b + c)^3 which will be a^3 + b^3 + c^3+3a^2 b+3a^2 c + 3b^2 c +3b^2 a +3c^2 a +3c^2 a+6abc.

Step-by-step explanation:

(a + b + c)^3 = a^3 + b^3 + c^3+3a^2 b+3a^2 c + 3b^2 c +3b^2 a +3c^2 a +3c^2 a+6abc.

Answer 2

Answer:

the identity is:

a3 + b3 + c3  = (a + b + c)(a2 + b2 + c2 - ab - bc - ca) + 3abc

if a+b+c=0,

a3+b3+c3 = 3abc
