How you do this i’m needing some on how to do this ? ?

Square one factor from column A: 
Add it to one factor from column B: 
Numerical Example Using the Identity:
x = 5 and y = 3
(5² + 2(5×3)+3²) + (5 - 3)² = 2(5)² + 2(3)²
(25 + 2(5×3)+9) + (2)² = 2(25) + 2(9)
(25 + 30 + 9) + 4 = 50 + 18
64 + 4 = 68
68 = 68
I would suggest using Pow Toons to make you video.  

C.1because in the function table shown when you plug -2 in for x your outcome is 1.
