integral from 0 to 2 of ((-x+5)-(x^2-9))

\int_{0}^{2} ((- x + 5) - (x^{2} - 9)) d x

\frac{70}{3}

Decimal Notation

23.33333 \dots

Solution steps

\int_{0}^{2} - x + 5 - (x^{2} - 9) d x

Simplify

= \int_{0}^{2} - x^{2} - x + 14 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} x^{2} d x - \int_{0}^{2} x d x + \int_{0}^{2} 14 d x

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

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

\int_{0}^{2} 14 d x = 28

= - \frac{8}{3} - 2 + 28

Simplify

- \frac{8}{3} - 2 + 28 : \frac{70}{3}

= \frac{70}{3}

\frac{d}{d x} (\frac{2 a}{x ^{3}})

\int \frac{12}{( x ^{2} - 9 )} d x

\int \frac{w ^{5}}{8 w ^{2} + 1} d w

f (x) = 3 x - 2 x^{2}, (- 2, - 14)

\frac{\partial}{\partial x} (- 6 x y - x^{6} - y^{6})
