integral of (2x+5)/(sqrt(x^2+5x))

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

2 x^{2} + 5 x + C

Solution steps

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

Apply u-substitution

: \int \frac{1}{u} d u

= \int \frac{1}{u} d u

Apply the Power Rule

: 2 u^{\frac{1}{2}}

= 2 u^{\frac{1}{2}}

Substitute back

u = x^{2} + 5 x

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

Apply radical rule:

= 2 x^{2} + 5 x

Add a constant to the solution

= 2 x^{2} + 5 x + C

f (x) = 7 + 5 x

y^{^{'}} = k \cdot y

\frac{( 3 t - 1 )}{t - 2}

y = \frac{4 x}{x + 2}

\frac{d}{d x} (ln (4 x y))
