What Is The Solution Set Of The Quadratic Inequality

Solve x 2 3x 2 0.

Solutions to inequality statements are ranges of numbers based on the inequality symbol. The general forms of the quadratic inequalities are. The function h 16t2 48t models the height h in feet of the stick above the ground after t seconds. A quadratic equation in standard form a b and c can have any value except that a can t be 0 the above is an equation but sometimes we need to solve inequalities like these.

There is no number that satisfiey this equation. The new twist is that instead of just two or fewer points. The coordinates of all points along the parabola as shown by the broken line belong to the solution set of the inequality. For example the inequality x 2 x 2 means that the unknown value x x is any real number less than 2 2.

Examples of quadratic inequalities are. Tim throws a stick straight up in the air from the ground. Ax 2 bx c 0. In other words the solution of a quadratic equation holds the same meaning that you are accustomed to.

Whenever you have a quadratic inequality where the associated quadratic equation does not have real solutions that is where the associated parabola does not cross the x axis the solution to the inequality will either be all x or no x depending upon whether the parabola is on the side of the axis that you need. First let us solve the given quadratic equation by factoring. The coordinates of all points along the parabola as shown by the broken line do not belong to the solution set of the inequality. Solve 3x2 18x 5 47 for x.

Shaded region belong to the solution set of the inequality. The solution is just where the graph crosses the x axis. The solutions to quadratic inequality always give the two roots. I and ii c.

The solution of a quadratic inequality are all of the points within the area y x 1 where y 0. Ii and iii b.
