integral of (e^{2x}-x)/(e^x)

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

e^{x} + \frac{x}{e ^{x}} + \frac{1}{e ^{x}} + C

Solution steps

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

Expand

\frac{e ^{2 x} - x}{e ^{x}} : e^{x} - \frac{x}{e ^{x}}

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

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

\int \frac{x}{e ^{x}} d x = - \frac{x}{e ^{x}} - \frac{1}{e ^{x}}

= e^{x} - (- \frac{x}{e ^{x}} - \frac{1}{e ^{x}})

Simplify

= e^{x} + \frac{x}{e ^{x}} + \frac{1}{e ^{x}}

Add a constant to the solution

= e^{x} + \frac{x}{e ^{x}} + \frac{1}{e ^{x}} + C

\int x (1 + x) d x

\int \frac{8}{9} csc^{2} (\frac{x}{9}) d x

\int (12 x^{2} + 6 x - 5) d x

\int \frac{5 x - 3}{x ^{2} + 7 x + 6} d x

\int \frac{3}{144 + 49 x ^{2}} d x
