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

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

2 x + y + 2

Solution steps

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

Treat

y

as a constant

Apply the Sum/Difference Rule:

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

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

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

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

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

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

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

= 2 x + y + 0 + 2 - 0

Simplify

= 2 x + y + 2
