z=yf(x)+xg(y)
Step-by-step explanation:
dz/dx=p=yf'(x)+g(y)
dz/dy =q=f(x)+xg'(y)
r=yf"(x)
s=f'(x))+g'(y)
px=xyf'(x)+xg'(y)
qy=yf(x)+xyg'(y)
px+qy=xy(f'(x)+g'(y))+xg(y)+yf(x)
px +qy=xys+z

We recall the concept of partial differentiation
Partial differentiation: A partial derivative of a function of several variables is its derivative with respect to one of them.
Given:
Thus both functions are eliminated
