integral of 3x^2+e^x-6

\int 3 x^{2} + e^{x} - 6 d x

x^{3} + e^{x} - 6 x + C

Solution steps

\int 3 x^{2} + e^{x} - 6 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 e^{x} d x - \int 6 d x

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

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

\int 6 d x = 6 x

= x^{3} + e^{x} - 6 x

Add a constant to the solution

= x^{3} + e^{x} - 6 x + C
