Are you looking for any of the below query? Quadratic equation is an important topic and frequently appears in various competitive exams. The presence of x 2 in the equation makes it quadratic else it will be called a linear equation. The number of questions asked from this topic range from 3 to 5. Therefore, candidates need to practice enough number of questions to develop an understanding of the topic. Quadratic equation can often be tricky and is generally where candidates make silly mistakes.

In this article we cover quadratic equations — definitions, formats, solved problems and sample questions for practice. A quadratic equation is a polynomial whose highest power is the square of a variable x 2 , y 2 etc. For every quadratic equation, there can be one or more than one solution. These are called the roots of the quadratic equation. We have to take two numbers adding which we get 5 and multiplying which we get 6. They are 2 and 3.

Let denominator be x ,the numerator x For an equation to have real roots, its discriminant should be greater than or equal to 0.

This calculator will solve any quadratic equation you type in even if solutions are imaginary. In the picture below, the left parabola has 2 real solutions red dots , the middle parabola has 1 real solution red dot and the right most parabola has no real solutions yes, it does have imaginary ones. The discriminant is a number that can be calculated from any quadratic equation. If the discriminant is a positive number, then there are 2 real solutions. This means that the graph of the parabola interepts the x-axis at 2 distinct points. If the discriminant is positive and also a perfect square like 64, then there are 2 real rational solutions. If the discriminant is positive and not a perfect square like 12, then there are 2 real ir rational solutions.
