Find the Integral xe^(2x)

Problem

(∫_^)(x*e(2*x)*d(x))

Solution

1. Identify the method of integration by parts, which uses the formula (∫_^)(u*d(v))=u*v−(∫_^)(v*d(u))

2. Choose the variables for substitution by letting u=x and d(v)=e(2*x)*d(x)

3. Differentiate u to find d(u)=d(x)

4. Integrate d(v) to find v=1/2*e(2*x)

5. Substitute these values into the integration by parts formula:

(∫_^)(x*e(2*x)*d(x))=x*(1/2*e(2*x))−(∫_^)(1/2*e(2*x)*d(x))

6. Evaluate the remaining integral:

(∫_^)(1/2*e(2*x)*d(x))=1/4*e(2*x)

7. Combine the terms and add the constant of integration C

1/2*x*e(2*x)−1/4*e(2*x)+C

Final Answer

(∫_^)(x*e(2*x)*d(x))=1/2*x*e(2*x)−1/4*e(2*x)+C
