integral of 3x^2-9x+5

integral

3 x^{2} - 9 x + 5

x^{3} - \frac{9 x ^{2}}{2} + 5 x + C

Solution steps

\int 3 x^{2} - 9 x + 5 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 3 x^{2} d x - \int 9 x d x + \int 5 d x

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

\int 9 x d x = \frac{9 x ^{2}}{2}

\int 5 d x = 5 x

= x^{3} - \frac{9 x ^{2}}{2} + 5 x

Add a constant to the solution

= x^{3} - \frac{9 x ^{2}}{2} + 5 x + C
