integral of 3x^2-e^x

Solution

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

Solution

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

Solution steps

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

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

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

Add a constant to the solution

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