\frac{d}{d x} (7 x^{3} + 3 x - 12)

21 x^{2} + 3

Solution steps

\frac{d}{d x} (7 x^{3} + 3 x - 12)

Apply the Sum/Difference Rule:

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

= \frac{d}{d x} (7 x^{3}) + \frac{d}{d x} (3 x) - \frac{d}{d x} (12)

\frac{d}{d x} (7 x^{3}) = 21 x^{2}

\frac{d}{d x} (3 x) = 3

\frac{d}{d x} (12) = 0

= 21 x^{2} + 3 - 0

Simplify

= 21 x^{2} + 3

\frac{d}{d x} (\frac{x}{4 x + 3 ln ( x )})

\int \frac{x ^{2}}{3 + x} d x

\frac{\partial}{\partial x} (3 x y z^{2})

s + 1

\int (4 x + 1)^{5} d x
