Expert Solution
Step 1

Partially differentiate with respect to x.

(x* + x')(x*)-x (x² + y²)* 2x(x + y? )- x² (2x) ) + و( تم+ y*) du ةx ةx 2.x + 2xy? – 2x (x' + y*} 2.xy² ) +ر(
Step 2

Partially differentiate with respect to y.

(x* + y°) (x*)-x*(x° + y*) (x° + y*)}° 0-x² (2y) (x² + x*)}° -2x'y (x* + y°)' ôy ôy ôu ây ||
