integral of (x+sqrt(x))^2+8e^{2x}

\int (x + x)^{2} + 8 e^{2 x} d x

\frac{x ^{3}}{3} + \frac{4}{5} x^{\frac{5}{2}} + \frac{x ^{2}}{2} + 4 e^{2 x} + C

Solution steps

\int (x + x)^{2} + 8 e^{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 (x + x)^{2} d x + \int 8 e^{2 x} d x

\int (x + x)^{2} d x = \frac{x ^{3}}{3} + \frac{4}{5} x^{\frac{5}{2}} + \frac{x ^{2}}{2}

\int 8 e^{2 x} d x = 4 e^{2 x}

= \frac{x ^{3}}{3} + \frac{4}{5} x^{\frac{5}{2}} + \frac{x ^{2}}{2} + 4 e^{2 x}

Add a constant to the solution

= \frac{x ^{3}}{3} + \frac{4}{5} x^{\frac{5}{2}} + \frac{x ^{2}}{2} + 4 e^{2 x} + C

\int \frac{5}{8 x - x ^{2}} d x

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

\int sin^{3} (x) sec^{3} (x) d x

\int \frac{2 x ^{2} - x + 1}{2 x ^{2} - 3 x + 1} d x

\int ln ∣ cos (x) ∣ d x
