【實用教育app】Equations and Inequalities solver - free|最夯免費app

This application solves the equations and inequalities of the second degree by the graphical method and the numerical method.Through the analysis of the sign of the coefficient of the variable of the second degree, and the delta, the roots are determined and, in the case of inequality, the range of solutions.For example (see the screenshoot), for the inequation:x ^ 2 + 3x + 2 equal to or greater than 0havingcoefficient of x ^ 2 greater than 0anddelta greater than 0the solution is determined constituted by the two intervals:x = or less than -2andx = to or greater than -1It will then assist you in correcting your exercises.The application solves in an immediate way all of the following combinations:ax ^ 2 + bx + c = or greater than 0ax ^ 2 + bx + c is greater than 0ax ^ 2 + bx + c = 0 ax ^ 2 + bx + c is less than 0ax ^ 2 + bx + c = 0 or less
