integral of x^2-2x-1

Solution

\int x^{2} - 2 x - 1 d x

Solution

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

Solution steps

\int x^{2} - 2 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 x^{2} d x - \int 2 x d x - \int 1 d x

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

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

\int 1 d x = x

= \frac{x ^{3}}{3} - x^{2} - x

Add a constant to the solution

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