What type of roots the equation has can be shown by the discriminant. The discriminant for a quadratic equation \(a{x^2} + bx + c = 0\) is \({b^2} - 4ac\). And the types of root the equation has ...

One significant area of recent research is the study of preperiodic points for quadratic polynomials. A preperiodic point is a point that eventually enters a periodic orbit under iteration of a ...

Recent research has focused on various aspects of these polynomials, including their relationships with differential equations ... but also characterized a quadratic class of Cauchy–Stieltjes ...
