integral of (x^2+2x+1)e^x

\int (x^{2} + 2 x + 1) e^{x} d x

e^{x} x^{2} + e^{x} + C

Solution steps

\int (x^{2} + 2 x + 1) e^{x} d x

Apply Integration By Parts

= (x^{2} + 2 x + 1) e^{x} - \int (2 x + 2) e^{x} d x

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

= (x^{2} + 2 x + 1) e^{x} - 2 e^{x} x

Simplify

(x^{2} + 2 x + 1) e^{x} - 2 e^{x} x : e^{x} x^{2} + e^{x}

= e^{x} x^{2} + e^{x}

Add a constant to the solution

= e^{x} x^{2} + e^{x} + C

\int \frac{x ^{4} - 3 x ^{2} - 3 x - 2}{x ^{3} - x ^{2} - 2 x} d x

\int \frac{1}{x ( x ^{10} + 1 )} d x

\int \frac{1}{x ^{4} x ^{2} + 1} d x

\int (2 x + 1)^{10} d x

\int \frac{x + 2}{2 x + 1} d x
