How to solve quadratic inequality equations
WebStep - 1: Write the inequality as an equation. Step - 2: Solve the equation for one or more values. Step - 3: Represent all the values on the number line. Step - 4: Also, represent all excluded values on the number line using open circles. Step - 5: Identify the intervals. WebTo solve a quadratic inequality, first convert it to standard form. Next, identify the case you are in, and find the zeros of the quadratic. Then, graph the corresponding parabola from the quadratic. Finally, shade the appropriate region on the graph based on signs and the inequality symbol.
