integral of xsqrt(x-5)

\int x x - 5 d x

\frac{2}{5} (x - 5)^{\frac{5}{2}} + \frac{10}{3} (x - 5)^{\frac{3}{2}} + C

Solution steps

\int x x - 5 d x

Apply u-substitution

: \int (u + 5) u d u

= \int (u + 5) u d u

Expand

(u + 5) u : u^{\frac{3}{2}} + 5 u

= \int u^{\frac{3}{2}} + 5 u d u

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int u^{\frac{3}{2}} d u + \int 5 u d u

\int u^{\frac{3}{2}} d u = \frac{2}{5} u^{\frac{5}{2}}

\int 5 u d u = \frac{10}{3} u^{\frac{3}{2}}

= \frac{2}{5} u^{\frac{5}{2}} + \frac{10}{3} u^{\frac{3}{2}}

Substitute back

u = x - 5

= \frac{2}{5} (x - 5)^{\frac{5}{2}} + \frac{10}{3} (x - 5)^{\frac{3}{2}}

Add a constant to the solution

= \frac{2}{5} (x - 5)^{\frac{5}{2}} + \frac{10}{3} (x - 5)^{\frac{3}{2}} + C

\frac{\partial}{\partial x} (x^{2} y + ln (x))

7 x^{2} - 3 x, x^{2} - 7 x + 2

x \to + 0 + lim (\frac{e ^{x}}{e ^{x} - 1})

\int \frac{28 e ^{4 t}}{6 + e ^{4 t}} d t

1 + cos (θ)
