integral of (x-6)^2

Solution

\int (x - 6)^{2} d x

Solution

\frac{x ^{3}}{3} - 6 x^{2} + 36 x + C

Solution steps

\int (x - 6)^{2} d x

Expand

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

= \int x^{2} - 12 x + 36 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 x^{2} d x - \int 12 x d x + \int 36 d x

\int x^{2} d x = \frac{x ^{3}}{3}

\int 12 x d x = 6 x^{2}

\int 36 d x = 36 x

= \frac{x ^{3}}{3} - 6 x^{2} + 36 x

Add a constant to the solution

= \frac{x ^{3}}{3} - 6 x^{2} + 36 x + C
