A space probe in the shape of the ellipsoid (4x² + y² + 4z² = 41) enters a planet's atmosphere and its surface begins to heat. After 1 hour, the temperature at the point (x, y, z) on the surface of the probe is given by the equation T(x, y, z) = 2x² + 3y² + 4z² + 5xy + 6xz + 7yz. Find the temperature at the point (1, 2, 3).
