This article will use three examples to show that assumption is incorrect. It follows then that when there are no real solutions to a quadratic equation the graph of the equation will have zero x-intercepts meaning that the parabola will never intersect the x-axis. If there is only one solution one says that it is a double root.
The general forms of the quadratic inequalities are.
Quadratic Formula If the expression under the square root is negative then the quadratic equation will have zero real solutions. A quadratic inequality is an equation of second degree that uses an inequality sign instead of an equal sign. X2 3x -1. Quadratic Formula If the expression under the square root is negative then the quadratic equation will have zero real solutions.
