derivative of

f (x) = (3 x + 1) (5 x - 4)

30 x - 7

Solution steps

\frac{d}{d x} ((3 x + 1) (5 x - 4))

Apply the Product Rule:

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

f = 3 x + 1, g = 5 x - 4

= \frac{d}{d x} (3 x + 1) (5 x - 4) + \frac{d}{d x} (5 x - 4) (3 x + 1)

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

\frac{d}{d x} (5 x - 4) = 5

= 3 (5 x - 4) + 5 (3 x + 1)

Simplify

3 (5 x - 4) + 5 (3 x + 1) : 30 x - 7

= 30 x - 7
