integral of (e^x+x^2-2^x)

\int (e^{x} + x^{2} - 2^{x}) d x

e^{x} + \frac{x ^{3}}{3} - \frac{2 ^{x}}{ln ( 2 )} + C

Solution steps

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

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

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

\int 2^{x} d x = \frac{2 ^{x}}{ln ( 2 )}

= e^{x} + \frac{x ^{3}}{3} - \frac{2 ^{x}}{ln ( 2 )}

Add a constant to the solution

= e^{x} + \frac{x ^{3}}{3} - \frac{2 ^{x}}{ln ( 2 )} + C
