Question

(a+b+c)^2 + (a-b-c)^2 + (-a-b-c)^2
solve these:​

Answer 1

Answer:

${{a}^{2} + {b}^{2} + {c }^{2} + 2ab + 2bc + 2ca} + {{a}^{2} + { - b}^{2} + { - c}^{2} + 2a( - b) + 2( - b)( - c) + 2( - c)a} + { { - a}^{2} + { - b}^{2} + { - c}^{2} + 2( - a)( - b) + 2( - b)( - c) + 2( - c)( - a)} \\ {a}^{2} + {b}^{2} + {c}^{2} + 2ab + 2bc + 2ca + {a}^{2} + {b}^{2} + {c}^{2} - 2ab + 2bc - 2ca + {a}^{2} + {b}^{2} + {c}^{2} + 2ab + 2bc + 2ca \\ 3 {a}^{2} + 3 {b}^{2} + 3 {c}^{2} + 2ab + 6bc + 2ca$
