Quadratic equations practice problems

Solve the equation by factoring:. Solve for :. This is a quadratic equation in standard form, so first we need to factor.

Here we will learn about the quadratic equation and how to solve quadratic equations using four methods: factorisation , using the quadratic equation formula , completing the square and using a graph. Quadratic algebraic equations are equations that contain terms up to x 2 ; the highest power for a quadratic equation is 2. Quadratic equations are a type of polynomial equation because they consist of two or more algebraic terms. A quadratic equation can have zero , one or two real solutions. At GCSE the solutions to polynomial equations such as quadratics will always give real numbers but they can be either irrational and rational numbers. Includes reasoning and applied questions. In order to solve a quadratic equation we must first check that it is in the form:.

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 us verify that.

Quadratic equation questions are provided here for Class 10 students. Here, a, b and c are constants, also called coefficients and x is an unknown variable. Also, learn Quadratic Formula here. Solving the problems based on quadratics will help students to understand the concept very well and also to score good marks in this section. All the questions are solved here step by step with a detailed explanation. In this article, we will give the definition and important formula for solving problems based on quadratic equations. Here, a and b are the coefficients of x 2 and x, respectively. So, basically, a quadratic equation is a polynomial whose highest degree is 2. Let us see some examples:. If we solve any quadratic equation, then the value we obtain are called the roots of the equation.
