integral of xsqrt(x^2-5)

\int x x^{2} - 5 d x

\frac{1}{3} (x^{2} - 5)^{\frac{3}{2}} + C

Solution steps

\int x x^{2} - 5 d x

Apply u-substitution

: \int u^{2} d u

= \int u^{2} d u

Apply the Power Rule

: \frac{u ^{3}}{3}

= \frac{u ^{3}}{3}

Substitute back

u = x^{2} - 5

= \frac{( x ^{2} - 5 ) ^{3}}{3}

Simplify

\frac{( x ^{2} - 5 ) ^{3}}{3} : \frac{1}{3} (x^{2} - 5)^{\frac{3}{2}}

= \frac{1}{3} (x^{2} - 5)^{\frac{3}{2}}

Add a constant to the solution

= \frac{1}{3} (x^{2} - 5)^{\frac{3}{2}} + C

x \to - 1 - lim (arccos (x))

\frac{d}{d x} (- x e^{- x})

\frac{d}{d x} (32 x)

x \to 0 + lim (10 x ln (x))

x \to 2 - lim (\frac{- 3}{x ^{2} - 4})
