HERE'S YOUR ANSWER.....✌️✌️
To solve these questions you need to use the formulas of algebra.
The formulas for these polynomials are :-
( a+b+c )^2 = a^2 + b^2 + c^2 + 2ab + 2bc + 2ca
( a+b-c )^2 = a^2 + b^2 + c^2 + 2ab + 2bc - 2ca
( a - b+c )^2 = a^2 + b^2 + c^2 - 2ab - 2bc + 2ca
( a-b-c )^2 = a^2 + b^2 + c^2 + 2ab - 2ca
Using these find the answers.
