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 Maths students, this video is for you! This is my first course on quadratic equations . Here, you will learn about i. How to solve a quadratic equation, using the formula. You can also solve it by direct factorisation, 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! iii. The rest of the course consists of 2 more lessons which can be shared with you, for a small fee. iv. These cover the nature of the roots of a quadratic equation. You will learn about the discriminant and how to tell if the roots are distinct , equal or imaginary depending on the nature of the discriminant. v. The course ends with a subtle reference to the sum and product of the roots of a quadratic equation, which is what Part 2 of this course will be about. Let this be one of the 5 things you will do in 2020! As I always insist, the only way to study Mathematics is by doing it. So, take a pen and paper and practice along!
