Step 1: Recognize that the integral involves the function (ln(x))^2. To solve this, we can use integration by parts, which is given by the formula: ∫ u dv = uv - ∫ v du. Choose u = (ln(x))^2 and dv = dx.
Step 2: Differentiate u = (ln(x))^2 to find du. Using the chain rule, du = 2 ln(x) * (1/x) dx = (2 ln(x)/x) dx. For dv = dx, integrate to find v = x.
Step 3: Substitute u, v, du, and dv into the integration by parts formula: ∫ (ln(x))^2 dx = x (ln(x))^2 - ∫ x * (2 ln(x)/x) dx.
Step 4: Simplify the remaining integral ∫ x * (2 ln(x)/x) dx. The x terms cancel, leaving ∫ 2 ln(x) dx. Use integration by parts again, choosing u = ln(x) and dv = dx.
Step 5: After performing the second integration by parts, combine all terms and include the constant of integration, C. The final expression will be x (ln(x))^2 - 2x ln(x) + 2x + C.
