integral from 0 to 2 of (12-x)sqrt(x)

\int_{0}^{2} (12 - x) x d x

162 - \frac{8 2}{5}

Decimal Notation

20.36467 \dots

Solution steps

\int_{0}^{2} (12 - x) x d x

Expand

(12 - x) x : 12 x - x^{\frac{3}{2}}

= \int_{0}^{2} 12 x - x^{\frac{3}{2}} 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_{0}^{2} 12 x d x - \int_{0}^{2} x^{\frac{3}{2}} d x

\int_{0}^{2} 12 x d x = 162

\int_{0}^{2} x^{\frac{3}{2}} d x = \frac{8 2}{5}

= 162 - \frac{8 2}{5}

\int_{0}^{1} 1 + 8 x^{2} d x

\int_{- x}^{x^{2} + 1} (x^{3} - x) d x

\int_{- 1}^{2} (x^{3} - 2 x^{2} - 5 x + 6) d x

\int_{0}^{3} x 1 + x^{2} d x

\int_{2}^{3} sin (\frac{π}{3} x) d x
