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.

This example can easily be Step 2: Factor with one of the following; If the given polynomial is a Binomial, factoring by one of the following 1. While this is a valid approach, it makes a simple problem appear complicated, which is, in general, not a good way to do mathematics. Such values are known as solutions or roots of the quadratic equation. The strategies presented for solving quadratic equations in this chapter were introduced at the end of Algebra. On the other hand, a quadratic equa -tion, when plotted, forms a curve.

When you throw a ball or shoot an arrow, fire a missile or throw a stone it goes up into the air, slowing as it travels, then comes down again faster and faster Ignoring air resistance, we can work out its height by adding up these three things: Note: t is time in seconds. This never happened! So our common sense says to ignore it. The method is explained in Graphing Quadratic Equations , and has two steps:.

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. Solve equations that are quadratic in form.

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.
