HELP ??? In economics, the Gini index of inequality (G), is one of the ways to measure the degree of concentration in the distribution of resources among members of a population. Is given by:

$$G=2\int\limits_{0}^{1}[x-L(x)]dx$$

The L (x) function is called Lorentz curve and Gini index (G) always has a value between 0 and 1, so that the smaller the index, the more uniform the distribution of income, and the higher the index , will be the most concentrated income in the hands of a few individuals. If, for a given population, the Lorentz curve is L(x)=0,8x^2+0,2x, calculate the Gini ind
