Hey there !
This is an implicit function.
Now. Differentiating with respect to y.
d/dy ( x² + 25 ) = d/dy ( 8y )
d(x²)/dx * dx/dy + 0 = 8*1
2x * dx/dy = 8
dx/dy = 8/2x .
dx/dy = 4/x .
Here, We use chain rule on d(x²)/dy and Sum rule : d(x+y)/da = d(x)/da + d(y)/da

Sorry, to say but this is not the right answer :
diffrentiation d/dy(8y) = 8 not one
