Question

The slope of the given line is: △ (PB) = 2 (OB) − 2 (OP)2 (PB) = 2 (13) − 2 (12)2 (PB) = 2 169 −144 = 25 PB = = 25 5 ∴ 2 × 5 = 10 2 2 2 + a +b +c 2 2 2 a +b +c −3abc 3 3 3 3 (2a −3) + 2 (3b + 4) + 2 (6c + 1) = 2 0 2a −3 = 0 a = 2 3 b = 3 −4 c = 6 −1 a + b + c = − 2 3 − 3 4 = 6 1 0 a + 3 b + 3 c − 3 3abc = (a + b + c)(a + 2 b + 2 c − 2 ab −bc −ac) a + 3 b + 3 c − 3 3abc = 0 ∴ = a +b +c 2 2 2 a +b +c −3abc 3 3 3 0
