derivative of x^3+3x^2-1

Solution

\frac{d}{d x} (x^{3} + 3 x^{2} - 1)

Solution

3 x^{2} + 6 x

Solution steps

\frac{d}{d x} (x^{3} + 3 x^{2} - 1)

Apply the Sum/Difference Rule:

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

= \frac{d}{d x} (x^{3}) + \frac{d}{d x} (3 x^{2}) - \frac{d}{d x} (1)

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

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

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

= 3 x^{2} + 6 x - 0

Simplify

= 3 x^{2} + 6 x
