integral of (9x^2-4x+5)

\int (9 x^{2} - 4 x + 5) d x

3 x^{3} - 2 x^{2} + 5 x + C

Solution steps

\int 9 x^{2} - 4 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 9 x^{2} d x - \int 4 x d x + \int 5 d x

\int 9 x^{2} d x = 3 x^{3}

\int 4 x d x = 2 x^{2}

\int 5 d x = 5 x

= 3 x^{3} - 2 x^{2} + 5 x

Add a constant to the solution

= 3 x^{3} - 2 x^{2} + 5 x + C
