Question

Simplify
(a+b+c)?
(a-b+c)² + (a+b-c)²

Answer 1

Answer:

[math](a+b+c)^2[/math] can be written as [math](a+b+c)*(a+b+c)[/math],

Therefore, [math](a+b+c)^2 = (a+b+c)*(a+b+c)[/math]

[math]= a(a+b+c) + b(a+b+c) + c(a+b+c)[/math]

[math]= a^2+ab+ca+ab+b^2+bc+ca+bc+c^2[/math]

[math]= a^2 + b^2 + c^2 + ab + ab + bc +bc + ca + ca[/math]

[math]= a^2 + b^2 + c^2 + 2ab + 2bc + 2ca[/math
