(\partial)/(\partial x)(x^2-y^2+z^2-2z-4)

\frac{\partial}{\partial x} (x^{2} - y^{2} + z^{2} - 2 z - 4)

2 x

Solution steps

\frac{\partial}{\partial x} (x^{2} - y^{2} + z^{2} - 2 z - 4)

Treat

y, z

as constants

Apply the Sum/Difference Rule:

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

= \frac{\partial}{\partial x} (x^{2}) - \frac{\partial}{\partial x} (y^{2}) + \frac{\partial}{\partial x} (z^{2}) - \frac{\partial}{\partial x} (2 z) - \frac{\partial}{\partial x} (4)

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

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

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

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

\frac{\partial}{\partial x} (4) = 0

= 2 x - 0 + 0 - 0 - 0

Simplify

= 2 x
