Since the integral $\int_{-2}^{1}\frac{x+2}{2x^2-4x}dx$ has a discontinuity inside the interval, we have to split it in two integrals

$\int_{-2}^{0}\frac{x+2}{2x^2-4x}dx+\int_{0}^{1}\frac{x+2}{2x^2-4x}dx$

Since the integral \int_{-2}^{1}\frac{x+2}{2x^2-4x}dx has a discontinuity inside the interval, we have to split it in two integrals. The integral \int_{-2}^{0}\frac{x+2}{2x^2-4x}dx results in: \int_{-2}^{0}\frac{x}{2x^2-4x}dx+\int_{-2}^{0}\frac{1}{x^2-2x}dx. Gather the results of all integrals. The integral \int_{0}^{1}\frac{x+2}{2x^2-4x}dx results in: \int_{0}^{1}\frac{x}{2x^2-4x}dx+\int_{0}^{1}\frac{1}{x^2-2x}dx.

Final answer to the problem

The integral diverges.
