Evaluate the indefinite integral:
\[
\int \frac{5 x^{4}-5 x}{x^{3}} d x=\square+C
\]
The final answer is \(\boxed{\frac{5 x^{2}}{2}+\frac{5}{x}+C}\).
Step 1 :First, we simplify the integral \(\int \frac{5 x^{4}-5 x}{x^{3}} d x\) as \(\int 5x dx - \int \frac{5}{x^2} dx\).
Step 2 :We then integrate the first term using the power rule, and the second term as the integral of a constant times x to the power of -2, also using the power rule.
Step 3 :The integral of the function is \(5x^2/2 + 5/x\).
Step 4 :Finally, we add the constant of integration, C, to our final answer.
Step 5 :The final answer is \(\boxed{\frac{5 x^{2}}{2}+\frac{5}{x}+C}\).
