Answer:

2a^{2} +4ab+4ac+2b^{2} +4bc+2c^{2}

Step-by-step explanation:

We want to simplify  (a+b+c)² +(a-b-c)²

To do this we need to distribute,

(a+b+c)*(a+b+c)= (a+b+c)^2: a^{2}+2ab+2ac+b^{2} +2bc+c^{2} \\((a+b+c)^2 a^{2}-2ab-2ac+b^{2} +4bc+c^{2}  \\combined: (a+b+c)^2 + (a+b+c)^2\\ 2a^{2} +4ab+4ac+2b^{2} +4bc+2c^{2}
