QUADRATIC EQUATIONS-SQUARE ROOT METHOD
Find the roots of sqrt(2)x*x +x +sqrt(2)=0? Divide 39 into 2 parts whose product is 338? Solve x^(2/3) - x^(1/3)-2=0 ? Solve x(x+2)(x+3)(x+5)=72 ? Watch this and more problems! What are quadratic equations? Most of us know that a quadratic equation is a degree 2 equation in one variable. For those of you who would like to learn more about quadratic equations and how to solve them and also for Class 11, ISC Math students, this video is for you! . Here, you will learn about i. How to solve a quadratic equation, using the formula. You can also solve it by direct factorization, but what happens if the correct factors don't click in your mind. ii. What happens if the equation is not a quadratic? Can it be converted to a quadratic? Most certainly, yes. Watch this video to know how! I am providing online classes topic wise and course wise. You can contact me for further details.
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.
SUM AND PRODUCT OF THE ROOTS OF A QUADRATIC EQUATION
Given a quadratic equation with roots p and q, find p/q and q/p? Find an equation whose roots are 3,-1/3. If p, q are the roots of a quadratic equation, form an equation whose roots are 2p and 2q. The ratio of the roots os x*x +px+q=0 is 2, find p and more problems!

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.
