integral of sqrt(x)(x-2)

\int x (x - 2) d x

\frac{2}{5} x^{\frac{5}{2}} - \frac{4}{3} x^{\frac{3}{2}} + C

Solution steps

\int x (x - 2) d x

Expand

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

= \int x^{\frac{3}{2}} - 2 x d x

Apply the Sum Rule:

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

= \int x^{\frac{3}{2}} d x - \int 2 x d x

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

\int 2 x d x = \frac{4}{3} x^{\frac{3}{2}}

= \frac{2}{5} x^{\frac{5}{2}} - \frac{4}{3} x^{\frac{3}{2}}

Add a constant to the solution

= \frac{2}{5} x^{\frac{5}{2}} - \frac{4}{3} x^{\frac{3}{2}} + C

4 \frac{d ^{2} y}{d x ^{2}} - 5 y = 0

x \to 4 lim (\frac{sin ( x )}{x})

\frac{d y}{d x}, y e^{y} \cdot \frac{x - 1}{x + 1} = \frac{x ^{3}}{3} - x

\int_{0}^{8} x d x

\frac{\partial}{\partial x} (x y arcsin (yz))
