(\partial)/(\partial x)(4y+9x^2)

\frac{\partial}{\partial x} (4 y + 9 x^{2})

18 x

Solution steps

\frac{\partial}{\partial x} (4 y + 9 x^{2})

Treat

y

as a constant

Apply the Sum/Difference Rule:

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

= \frac{\partial}{\partial x} (4 y) + \frac{\partial}{\partial x} (9 x^{2})

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

\frac{\partial}{\partial x} (9 x^{2}) = 18 x

= 0 + 18 x

Simplify

= 18 x
