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

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

2 y

Solution steps

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

Treat

x

as a constant

Apply the Sum/Difference Rule:

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

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

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

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

= 2 y - 0

Simplify

= 2 y
