derivative of

4 7 x^{2} + 5

\frac{28 x}{7 x ^{2} + 5}

Solution steps

\frac{d}{d x} (4 7 x^{2} + 5)

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= 4 \frac{d}{d x} (7 x^{2} + 5)

Apply the chain rule:

\frac{1}{2 7 x ^{2} + 5} \frac{d}{d x} (7 x^{2} + 5)

= \frac{1}{2 7 x ^{2} + 5} \frac{d}{d x} (7 x^{2} + 5)

\frac{d}{d x} (7 x^{2} + 5) = 14 x

= 4 \cdot \frac{1}{2 7 x ^{2} + 5} \cdot 14 x

Simplify

4 \cdot \frac{1}{2 7 x ^{2} + 5} \cdot 14 x : \frac{28 x}{7 x ^{2} + 5}

= \frac{28 x}{7 x ^{2} + 5}
