Graph and solve quadratic inequalities
WebExplore math with our beautiful, free online graphing calculator. Graph functions, plot points, visualize algebraic equations, add sliders, animate graphs, and more. WebThe solutions of the quadratic inequalities in each of the previous examples, were either an interval or the union of two intervals. This resulted from the fact that, in each case we found two solutions to the corresponding quadratic equation ax 2 + bx + c = 0. These two solutions then gave us either the two x-intercepts for the graph or the two critical points …

Our inequality was x^2 +4x -5 > 0. We know that in x = -5 and x = 1 the expression is equal to zero. We must have that the expression is larger than zero and therefore we need the regions left from the smallest root and right of the largest root. Our solution will then be: bitesize parts of a flowerWebHow do you solve quadratic inequalities?
