integral from 1 to 4 of x-(x-2)^2

\int_{1}^{4} x - (x - 2)^{2} d x

\frac{9}{2}

Decimal Notation

4.5

Solution steps

\int_{1}^{4} x - (x - 2)^{2} d x

Expand

x - (x - 2)^{2} : - x^{2} + 5 x - 4

= \int_{1}^{4} - x^{2} + 5 x - 4 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_{1}^{4} x^{2} d x + \int_{1}^{4} 5 x d x - \int_{1}^{4} 4 d x

\int_{1}^{4} x^{2} d x = 21

\int_{1}^{4} 5 x d x = \frac{75}{2}

\int_{1}^{4} 4 d x = 12

= - 21 + \frac{75}{2} - 12

Simplify

- 21 + \frac{75}{2} - 12 : \frac{9}{2}

= \frac{9}{2}

x \to 2 lim ((6 - x) - 2)

\frac{d}{d x} (\frac{90}{x ^{9}})

\int x 3 x + 1 d x

\int_{5}^{\infty} \frac{1}{x ^{2} + x} d x
