For a quadratic equation to have real roots, discriminant must be more than or equal 0. Note the emphasize on “more than or equal to”. Set up this equality and solve it, you will get the answer. One important thing to note is that for real roots, it also means that a line intersects a given curve. […]

For a quadratic equation to have no real roots, discriminant must be less than 0. Set up this equality and solve it, you will get the answer. One important thing to note is that for no real roots, it also means that a line does not intersect a given curve. Let’s move on to understand more about real

For a quadratic equation to have two equal real roots, discriminant must be equal to 0. Set up this equality and solve it, you will get the answer. One important thing to note is that for two equal real roots, it also means that a line does not  Let’s move on to understand more about no real roots.

For a quadratic equation to have two distinct real roots, discriminant must be more than 0. Set up this inequality and solve it, you will get the answer. One important thing to note is that for two distinct real roots, it also means that a line intersects a given curve at two points. Let’s move

In this post, you will see an example where the discriminant is less than 0. A quick recap: discriminant less than 0 means no real roots. Let’s move on to understand more about two distinct real roots. If you are looking for math tuition, please visit Odyssey Math Tuition Singapore for more information. More math topics explained.

In this post, you will see an example where the discriminant is more than 0. A quick recap: discriminant more than 0 means 2 distinct real roots. Let’s move on to see an example on discriminant equal to 0. If you are looking for math tuition, please visit Odyssey Math Tuition Singapore for more information. More math topics explained. Odyssey

Discriminant of a Quadratic Equation is a new concept that you have to learn in Secondary 3 Additional Mathematics. This concept will be tested over and over again in exams and in this post, you will understand the fundamentals of discriminant. A very quick summary on what you will be learning here: 1) If discriminant

Previously, you have learnt how to solve quadratic inequalities where the portion of the curve is below the x-axis. In this post, you will be learning how to solve quadratic inequalities where the portion of the curve is above the x-axis. Not to worry, the solving style is the same, so there is not much new

Earlier, you have recapped on basic inequalities. In this post, you will learn how to solve quadratic inequalities where the portion of the curve is below the x-axis. Now that you have learnt how to solve quadratic inequalities for the portion of the curve below the x-axis, let’s move on to solve quadratic inequalities where the
