15\textit{x}^2 - 35\textit{x} + 25 Let $f(x) = \frac{15x^2 - 35x + 25}{(x - 1)(x - 2)^2}$. The partial fraction decomposition of $f(x) = \frac{A}{(x - 1)} + \frac{B}{(x - 2)} + \frac{C}{(x - 2)^2}$, where $A, B, C \in \mathbb{Z}$. Work out the values of A, B and C. A = B = C = Use the partial fraction decomposition of $f(x)$ to work out $\int f(x) \, dx$. Write your answer in the form $5 \ln|x - 1| + T \ln|x - 2| + U(x - 2)^{-1} + C$ where C is the constant of integration T = U = V =
