Answer:
see explanation
Step-by-step explanation:
(a + b + c)² = (a + b + c)(a + b + c)
Each term in the second factor is multiplied by each term in the firs factor, that is
a(a + b + c) + b(a + b + c) + c(a + b + c) ← distribute all 3 parenthesis
= a² + ab + ac + ab + b² + bc + ac + bc + c² ← collect like terms
= a² + b² + c² + 2ab + 2bc + 2ac
