derivative of x^4-20x^2+64

Solution

\frac{d}{d x} (x^{4} - 20 x^{2} + 64)

Solution

4 x^{3} - 40 x

Solution steps

\frac{d}{d x} (x^{4} - 20 x^{2} + 64)

Apply the Sum/Difference Rule:

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

= \frac{d}{d x} (x^{4}) - \frac{d}{d x} (20 x^{2}) + \frac{d}{d x} (64)

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

\frac{d}{d x} (20 x^{2}) = 40 x

\frac{d}{d x} (64) = 0

= 4 x^{3} - 40 x + 0

Simplify

= 4 x^{3} - 40 x
