integral from-4 to-3 of x^2-(2x+15)

\int_{- 4}^{- 3} x^{2} - (2 x + 15) d x

\frac{13}{3}

Decimal Notation

4.33333 \dots

Solution steps

\int_{- 4}^{- 3} x^{2} - (2 x + 15) d x

Simplify

= \int_{- 4}^{- 3} x^{2} - 2 x - 15 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_{- 4}^{- 3} x^{2} d x - \int_{- 4}^{- 3} 2 x d x - \int_{- 4}^{- 3} 15 d x

\int_{- 4}^{- 3} x^{2} d x = \frac{37}{3}

\int_{- 4}^{- 3} 2 x d x = - 7

\int_{- 4}^{- 3} 15 d x = 15

= \frac{37}{3} - (- 7) - 15

Simplify

\frac{37}{3} - (- 7) - 15 : \frac{13}{3}

= \frac{13}{3}

\int_{0}^{2} 2 x (x^{2} - 1)^{3} d x

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

\int_{0}^{1} 3^{x} e^{x} d x

\int_{1}^{x^{2}} e^{- t^{2}} d t

\int_{- 4}^{1} ∣ x + 2 ∣ d x
