\frac{d}{d x} (x^{4} - 3 x^{2} + 4)

4 x^{3} - 6 x

Solution steps

\frac{d}{d x} (x^{4} - 3 x^{2} + 4)

Apply the Sum/Difference Rule:

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

= \frac{d}{d x} (x^{4}) - \frac{d}{d x} (3 x^{2}) + \frac{d}{d x} (4)

\frac{d}{d x} (x^{4}) = 4 x^{3}

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

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

= 4 x^{3} - 6 x + 0

Simplify

= 4 x^{3} - 6 x
