\frac{d}{d x} ((x^{3} + 3 x) (2 x + 4))

8 x^{3} + 12 x^{2} + 12 x + 12

Solution steps

\frac{d}{d x} ((x^{3} + 3 x) (2 x + 4))

Apply the Product Rule:

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

f = x^{3} + 3 x, g = 2 x + 4

= \frac{d}{d x} (x^{3} + 3 x) (2 x + 4) + \frac{d}{d x} (2 x + 4) (x^{3} + 3 x)

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

\frac{d}{d x} (2 x + 4) = 2

= (3 x^{2} + 3) (2 x + 4) + 2 (x^{3} + 3 x)

Simplify

(3 x^{2} + 3) (2 x + 4) + 2 (x^{3} + 3 x) : 8 x^{3} + 12 x^{2} + 12 x + 12

= 8 x^{3} + 12 x^{2} + 12 x + 12

\int y y d y

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

x \to \infty lim (\frac{3}{x})

n = 0 \sum \infty 1 - (\frac{2}{3})^{n}

x \to 4 lim (x^{2} + 2 x + 2)
