integral of 2x^2-x+1

Solution

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

Solution

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

Solution steps

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

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

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

\int 1 d x = x

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

Add a constant to the solution

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