Answer 2

Step-by-step explanation:

Lets proceed

(a+b+c) ^2

=(a+b+c)* (a+b+c) ;

=a*a + a*b + a*c + b*a + b*b + b*c + c*a + c*b + c*c;

=a^2 + ab + ac + ba + b^2 + bc + ca + cb + c^2;

=a^2 + b^2 +c^2 + ab +ba +bc +cb + ac + ca ;

=a^2 + b^2 + c^2 + 2ab + 2bc + 2ca;

So here we got the final result.

Therefore,

(a+b+c) ^2 = a^2 +b^2 + c^2 + 2ab + 2bc + 2ca.

Thank you.
