derivative of f(x)=sqrt(5x+x^2)

Solution

derivative of

f (x) = 5 x + x^{2}

Solution

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

Solution steps

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

Apply the chain rule:

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

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

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

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

Simplify

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

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