NATURE OF THE ROOTS OF A QUADRATIC EQUATION
What is the Discriminant of a Quadratic Equation? You will see how to calculate the discriminant and find the nature of the roots of the quadratic, depending on whether D > 0. D = 0 or D < 0. Different cases when D is a perfect square or not are also discussed.
PROBLEMS-NATURE OF THE ROOTS OF A QUADRATIC EQUATION
Presenting a few problems on nature of the roots of a quadratic equation. Given the nature of the roots, you will see how other parameters can be determined.
HOW TO FORM A QUADRATIC EQUATION GIVEN THE ROOTS
Given 2 roots of a quadratic equation, you will learn how to form the equation using a simple formula. 2 problems are solved here. A very profound concept.
SOLVING QUADRATIC INEQUALITIES
Learn how quadratic inequalities can be solved using the method of intervals. Note how this method works only if the coefficient of the highest degree term is non negative. This is extensively used in Calculus, Applications of Derivatives.
