(\partial)/(\partial x)((3x^2+5x+1)(y+4))

\frac{\partial}{\partial x} ((3 x^{2} + 5 x + 1) (y + 4))

(y + 4) (6 x + 5)

Solution steps

\frac{\partial}{\partial x} ((3 x^{2} + 5 x + 1) (y + 4))

Treat

y

as a constant

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= (y + 4) \frac{\partial}{\partial x} (3 x^{2} + 5 x + 1)

Apply the Sum/Difference Rule:

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

= (y + 4) (\frac{\partial}{\partial x} (3 x^{2}) + \frac{\partial}{\partial x} (5 x) + \frac{\partial}{\partial x} (1))

\frac{\partial}{\partial x} (3 x^{2}) = 6 x

\frac{\partial}{\partial x} (5 x) = 5

\frac{\partial}{\partial x} (1) = 0

= (y + 4) (6 x + 5 + 0)

Simplify

= (y + 4) (6 x + 5)
