integral from 2 to 5 of-x^2+7x-10

\int_{2}^{5} - x^{2} + 7 x - 10 d x

\frac{9}{2}

Decimal

4.5

Solution steps

\int_{2}^{5} - x^{2} + 7 x - 10 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_{2}^{5} x^{2} d x + \int_{2}^{5} 7 x d x - \int_{2}^{5} 10 d x

\int_{2}^{5} x^{2} d x = 39

\int_{2}^{5} 7 x d x = \frac{147}{2}

\int_{2}^{5} 10 d x = 30

= - 39 + \frac{147}{2} - 30

Simplify

- 39 + \frac{147}{2} - 30 : \frac{9}{2}

= \frac{9}{2}

- 4 sin (4 t)

\frac{6}{( s - 2 ) ^{2} ( s - 4 ) ^{4}}

x \frac{d y}{d x} + 1 = x + y

\frac{\partial}{\partial y} (6 - 3 x - 2 y)

\int_{- \infty}^{- 1} e^{- 34 t} d t
