Choose u and dv: To solve the integral of 6xe(x+2) with respect to x, we will use integration by parts, which is based on the formula ∫udv=uv−∫vdu. We need to choose u and dv such that the resulting integral is simpler to solve.Let's choose u=6x and dv=e(x+2)dx.
Find du and v: We need to find du and v. Differentiating u with respect to x gives us du=6dx. Integrating dv with respect to x gives us v=e(x+2).
Apply integration by parts: Now we apply the integration by parts formula:∫udv=uv−∫vdu∫6xe(x+2)dx=6x⋅e(x+2)−∫e(x+2)⋅6dx
Integrate the second term: We can now integrate the second term:∫e(x+2)⋅6dx=6⋅∫e(x+2)dxTo integrate e(x+2), we use the fact that the integral of ex is ex. Therefore, the integral of e(x+2) is also e(x+2).
Substitute back into formula: So the integral of 6e(x+2)dx is 6e(x+2). Now we can substitute this back into our integration by parts formula: ∫6xe(x+2)dx=6x⋅e(x+2)−6⋅e(x+2)
Simplify the expression: We can simplify the expression:∫6xe(x+2)dx=6xe(x+2)−6e(x+2)+CHere, C is the constant of integration.
Final indefinite integral: We have now found the indefinite integral of 6xe(x+2) with respect to x: ∫6xe(x+2)dx=6xe(x+2)−6e(x+2)+C
