+4622 Discriminant is used to find the number of real roots of a quadratic equation and also the nature of the roots of a quadratic equation. Discriminant analysis is used to analyze relationships between a non-metric dependent variable and metric or dichotomous independent variables.
For a quadratic equation of the form ax^2 + bx + c = 0 with real number coefficients and a not equal to 0, the expression b^2 - 4ac is called the discriminant and can be used to determine the number and type of the solution of the equation.
So, the answer is \(\boxed{-23}\)
