(\partial)/(\partial y)(x^2-2x-xy)

\frac{\partial}{\partial y} (x^{2} - 2 x - x y)

- x

Solution steps

\frac{\partial}{\partial y} (x^{2} - 2 x - x y)

Treat

x

as a constant

Apply the Sum/Difference Rule:

(f \pm g)^{'} = f^{'} \pm g^{'}

= \frac{\partial}{\partial y} (x^{2}) - \frac{\partial}{\partial y} (2 x) - \frac{\partial}{\partial y} (x y)

\frac{\partial}{\partial y} (x^{2}) = 0

\frac{\partial}{\partial y} (2 x) = 0

\frac{\partial}{\partial y} (x y) = x

= 0 - 0 - x

Simplify

= - x
