1.	Let the plane ax+by+cz+d=0 bisect the line joining the points (4,–3,1) and (2,3,–5) at the right angles. If a,b,c,d are integers, then the minimum value of (a2+b2+c2+d2) is
Answer» Let the plane $a x + b y + c z + d = 0$ bisect the line joining the points $(4, - 3, 1)$ and $(2, 3, - 5)$ at the right angles. If $a, b, c, d$ are integers, then the minimum value of $(a^{2} + b^{2} + c^{2} + d^{2})$ is
