integral from 0 to 6 of (6-x)^2

Solution

\int_{0}^{6} (6 - x)^{2} d x

Solution

72

Solution steps

\int_{0}^{6} (6 - x)^{2} d x

Expand

(6 - x)^{2} : 36 - 12 x + x^{2}

= \int_{0}^{6} 36 - 12 x + x^{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}^{6} 36 d x - \int_{0}^{6} 12 x d x + \int_{0}^{6} x^{2} d x

\int_{0}^{6} 36 d x = 216

\int_{0}^{6} 12 x d x = 216

\int_{0}^{6} x^{2} d x = 72

= 216 - 216 + 72

Simplify

= 72
