    Does the quadratic equation x2 4x + 8 0 have real solutions?
    Again, remember that the number under the square root is the discriminant. In this case the discriminant is −16. It is not possible to square a real number and get −16. Thus, the quadratic equation x^2 − 4x + 8 = 0 has no real solutions, as predicted. Let’s summarize the findings in our last three examples.

    What is x2 + x 6 = 0?
    The equation x2 + x − 6 = 0 is in standard form. We can use the zero-product property to solve quadratic equations in which we first have to factor out the greatest common factor (GCF), and for equations that have special factoring formulas as well, such as the difference of squares, both of which we will see later in this section.

    Does x2 = 4 have real solutions?
    The equation x2 = − 4 has no real solutions.4 It is not possible to square a real number and get −4. In this situation, we will simply state that “the equation x2 = − 4 has no real solutions (no solutions that are real numbers).” Find all real solutions of the equations x2 = 30, x2 = 0, andx2 = − 14.

    What is a quadratic equation ax2 + bx + c = 0?
    The solution (9) is called the quadratic formula. The solutions to the quadratic equation ax2 + bx + c = 0 are given by the quadratic formula x = − b ± √b2 − 4ac 2a Although the development of the quadratic formula can be intimidating, in practice its application is quite simple. Let’s look at some examples.
