derivative of

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

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

Solution steps

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

Apply the chain rule:

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

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

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

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

Simplify

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

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