integral of 3x^2+2x-5

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

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

Solution steps

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

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

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

\int 5 d x = 5 x

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

Add a constant to the solution

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