Subtract 4a^(2) + 5b^(2) - 6c^(2) + 8 from 2a^(2) -3b^(2) - 4c^(2) - 5 .

det [[a ^ (2), bc, c ^ (2) + caa ^ (2) + ab, b ^ (2), caab, b ^ (2) + bc, c ^ (2)]] = 4a ^ (2) b ^ (2) c ^ (2)

4 (bc * cos ^ (2) ((A) / (2)) + cos ^ (2) ((B) / (2)) + ab * cos ^ (2) ((C) / (2)) ) = (a + b + c) ^ (2)

If a, b, c are non zero complex numbers satisfying a^(2) + b^(2) + c^(2) = 0 and |(b^(2) + c^(2),ab,ac),(ab,c^(2) + a^(2),bc),(ac,bc,a^(2) + b^(2))| = k a^(2) b^(2) c^(2) , then k is equal to

(bc) / (a) cos ^ (2) ((A) / (2)) + (ca) / (b) cos ^ (2) ((B) / (2)) + (ab) / (c ) cos ^ (2) ((C) / (2)) =

(bc) / (a) cos ^ (2) ((A) / (2)) + (ca) / (b) cos ^ (2) ((B) / (2)) + (ab) / (c ) cos ^ (2) ((C) / (2)) =
