Question

I need help to better understand how the solution to this problem is acquired.

Find the linearization L(x,y) of the function f(x,y) = x? - 4xy + 5 at Po(5,4). Then find an upper bound for the magnitude |E| of the error in the approximation f(x,y)×L(x,y) over the rectangle R: |x- 5| s0.5, ly - 4|s0.5.
The linearization of f is L(x,y) = - 6x – 20y + 60.
The upper bound for the error of approximation is E(x.y)s 2.
(Round to the nearest hundredth as needed.)
