Here we will learn about the quadratic equation and how to solve quadratic equations using four methods: factorisationusing the quadratic quadratic equations practice problems formulacompleting 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 zeroone or two real solutions.

Solve the equation by factoring:. Solve for :. This is a quadratic equation in standard form, so first we need to factor. By trial and error we find that , so. The solution set is. The above triangular sail has area square feet. What is?

If the coefficients of all three terms have a common factor, pull it out. In other words, we need to rearrange the euqation. Multiply the first coefficient by the final term and list off factors. There are two ways to do this. One way involves using the quadratic formula. The quadratic formula is written below. Plug these values into the quadratic equation to find x. Note that. This is our answer by the first merthod. Billy is several years older than Johnny. Billy is one less than twice as old as Johnny, and their ages multiplied together make ninety-one.

For this kind of equations, we apply the quadratic formula to find the roots.

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.
