I made an error calculating the terms. The answer is 21.66 of course.

You simply subtract 1 (r2) from 2 (r3) and you get 1

can you do that?
Aren't we supposed to do an operation on 1 (here you do an operation on 2)

with 2 and 3 it is not, it is problematic. for the sake of the exercise, ignore

((50-55.022)^2 / 55.022) + ((57-45.628)^2/ 45.628)+ ((15-21.35)^2/21.35) = 5.181

Any complaints?

Isn't the second derivative of L''yx = 1 - 2Lagrange ? It's noted as 1 - Lagrange
