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
