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

\frac{15 x ^{2} + 4 x}{2 3 x + 1}

Solution steps

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

Apply the Product Rule:

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

f = x^{2}, g = 3 x + 1

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

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

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

= 2 x 3 x + 1 + \frac{3}{2 3 x + 1} x^{2}

Simplify

2 x 3 x + 1 + \frac{3}{2 3 x + 1} x^{2} : \frac{15 x ^{2} + 4 x}{2 3 x + 1}

= \frac{15 x ^{2} + 4 x}{2 3 x + 1}
