integral of (x^2-2)sqrt(x^3-6x+3)

\int (x^{2} - 2) x^{3} - 6 x + 3 d x

\frac{2}{9} (x^{3} - 6 x + 3)^{\frac{3}{2}} + C

Solution steps

\int (x^{2} - 2) x^{3} - 6 x + 3 d x

Apply u-substitution

: \int \frac{u}{3} d u

= \int \frac{u}{3} d u

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= \frac{1}{3} \cdot \int u d u

Apply the Power Rule

: \frac{2}{3} u^{\frac{3}{2}}

= \frac{1}{3} \cdot \frac{2}{3} u^{\frac{3}{2}}

Substitute back

u = x^{3} - 6 x + 3

= \frac{1}{3} \cdot \frac{2}{3} (x^{3} - 6 x + 3)^{\frac{3}{2}}

Simplify

\frac{1}{3} \cdot \frac{2}{3} (x^{3} - 6 x + 3)^{\frac{3}{2}} : \frac{2}{9} (x^{3} - 6 x + 3)^{\frac{3}{2}}

= \frac{2}{9} (x^{3} - 6 x + 3)^{\frac{3}{2}}

Add a constant to the solution

= \frac{2}{9} (x^{3} - 6 x + 3)^{\frac{3}{2}} + C

\int \frac{1}{- v ^{2}} d v

\frac{d}{d x} (lo g_{2} (x^{2} + 1) - 2^{3})

\int 3 x e^{7 x^{2}} d x

x \to 2 - lim (ln (x - 2))

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