I need a detailed step-by-step solution for the following calculus question:
1. Find the derivative of f(x) = (3x + 5x – 2) / (x + 1)
2. Find the indefinite integral of f(x) = x + 2x – 5x + 7
Please explain each step clearly, especially the quotient rule and integration by parts if used. Also show the final answer.
I have an exam tomorrow, so I need clear explanations.
