integral from 0 to 6 of (2x-1)^2

Solution

\int_{0}^{6} (2 x - 1)^{2} d x

Solution

222

Solution steps

\int_{0}^{6} (2 x - 1)^{2} d x

Expand

(2 x - 1)^{2} : 4 x^{2} - 4 x + 1

= \int_{0}^{6} 4 x^{2} - 4 x + 1 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} 4 x^{2} d x - \int_{0}^{6} 4 x d x + \int_{0}^{6} 1 d x

\int_{0}^{6} 4 x^{2} d x = 288

\int_{0}^{6} 4 x d x = 72

\int_{0}^{6} 1 d x = 6

= 288 - 72 + 6

Simplify

= 222
