extreme (x^2+4)/(x^2-25)

Solution

extreme points

\frac{x ^{2} + 4}{x ^{2} - 25}

Solution

Maximum (0, - \frac{4}{25})

Solution steps

f^{'} (x) = - \frac{58 x}{( x ^{2} - 25 ) ^{2}}

Find intervals:

Increasing

: - \infty < x < - 5,

Increasing

: - 5 < x < 0,

Decreasing

: 0 < x < 5,

Decreasing

: 5 < x < \infty

Plug

x = 0

into

\frac{x ^{2} + 4}{x ^{2} - 25} : - \frac{4}{25}

Maximum (0, - \frac{4}{25})
