$\int\left(-21x+\frac{1}{x}\right)dx$
Learn how to solve integral calculus problems step by step online. Find the integral int(-21*1x+1/x)dx. Simplifying. Expand the integral \int\left(-21x+\frac{1}{x}\right)dx into 2 integrals using the sum rule for integrals, to then solve each integral separately. The integral \int-21xdx results in: -\frac{21}{2}x^2. The integral \int\frac{1}{x}dx results in: \ln\left(x\right).
Final Answer
$-\frac{21}{2}x^2+\ln\left(x\right)+C_0$
