derivative of (x-4(x+1)(x+5))

Solution

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

Solution

3 x^{2} + 4 x - 19

Solution steps

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

Apply the Product Rule:

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

f = x - 4, g = (x + 1) (x + 5)

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

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

\frac{d}{d x} ((x + 1) (x + 5)) = 2 x + 6

= 1 \cdot (x + 1) (x + 5) + (2 x + 6) (x - 4)

Simplify

1 \cdot (x + 1) (x + 5) + (2 x + 6) (x - 4) : 3 x^{2} + 4 x - 19

= 3 x^{2} + 4 x - 19
