Learn how to solve problems step by step online. Find the derivative d/dx((x^2+2x)/(e^x)). Wenden Sie die Formel an: \frac{d}{dx}\left(\frac{a}{b}\right)=\frac{\frac{d}{dx}\left(a\right)b-a\frac{d}{dx}\left(b\right)}{b^2}, wobei a=x^2+2x und b=e^x. Simplify \left(e^x\right)^2 using the power of a power property: \left(a^m\right)^n=a^{m\cdot n}. In the expression, m equals x and n equals 2. Wenden Sie die Formel an: -\left(a+b\right)=-a-b, wobei a=x^2, b=2x, -1.0=-1 und a+b=x^2+2x. Wenden Sie die Formel an: \frac{d}{dx}\left(e^x\right)=e^x.
