Final answer:
The integral of (x - 1)² dx is evaluated using the power rule for integration, resulting in 1/3 (x-1)³ + C, where C is the constant of integration.
Step-by-step explanation:
The integral in question is ∫f(x² - 6x + 5) dx, which is equivalent to the integral of (x - 1)² dx. To solve this, we apply the power rule for integration. The integral of (x - 1)² dx is given by ∫(x - 1)² dx = 1/3 (x - 1)³ + C, where C is the constant of integration. Therefore, the correct evaluation of the integral is 1/3 (x−1)³ + C.
