derivative of

x (3 x - 4)

\frac{9 x - 4}{2 x}

Solution steps

\frac{d}{d x} (x (3 x - 4))

Apply the Product Rule:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = x, g = 3 x - 4

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

\frac{d}{d x} (x) = \frac{1}{2 x}

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

= \frac{1}{2 x} (3 x - 4) + 3 x

Simplify

\frac{1}{2 x} (3 x - 4) + 3 x : \frac{9 x - 4}{2 x}

= \frac{9 x - 4}{2 x}
