10. Solutions Or Roots Of Quadratic Equations Solutions or Roots of quadratic equations. Consider the quadratic equation. A real number x will be called a solution or a root if http://www.sosmath.com/algebra/quadraticeq/root/root.html

Solutions or Roots of Quadratic Equations Consider the quadratic equation A real number x will be called a solution or a root if it satisfies the equation, meaning . It is easy to see that the roots are exactly the x-intercepts of the quadratic function , that is the intersection between the graph of the quadratic function with the x-axis. Example 1: Find the roots of the equation Solution. This equation is equivalent to Since 1 has two square-roots , the solutions for this equation are Example 2: Find the roots of the equation Solution. This example is somehow trickier than the previous one but we will see how to work it out in the general case. First note that we have Therefore the equation is equivalent to which is the same as Since 3 has two square-roots , we get which give the solutions to the equation We may then wonder whether any quadratic equation may be reduced to the simplest ones described in the previous examples. The answer is somehow more complicated but it was known for a very longtime (to the Babylonians about 2000 B.C. ). Their idea was based mainly on completing the square which we did in solving the second example.

Abu Ja'far al-Khwarizmi Abu Ja'far al-Khwarizmi was an Arab mathematician who lived between AD 780 and 850. At a time when the spread of ideas was difficult, al-Khwarizmi wrote a book which contained many important mathematical concepts of the Middle East. This book changed all of European mathematics, introducing the decimal system and rules for doing algebra.

Quadratic Equation Solver Quadratic equations have the form ax bx c They will generally have two solutions; that is, two different values of x that make the equation true. It can happen that both solutions are the same number, and it is possible that the solutions will be complex or imaginary numbers. To use this utility, you type in values for a b , and c in the boxes below, and press the Solve button. You may enter positive, negative, or zero values, but the value of a cannot be zero.

(Back to the College Algebra Homepage) (Back to the GRE Math Help Page) (Back to the THEA Math Help Page) College Algebra Tutorial 17: Quadratic Equations Learning Objectives After completing this tutorial, you should be able to: Solve quadratic equations by factoring. Solve quadratic equations by the square root method. Solve quadratic equations by completing the square. Solve quadratic equations by using the quadratic formula. Find the discriminant of a quadratic equation and use it to tell how many and what type of solutions the equation has. Introduction In this tutorial, we will be looking at solving a specific type of equation called the quadratic equation. The methods of solving these types of equations that we will take a look at are solving by factoring, by using the square root method, by completing the square, and by using the quadratic equation. Sometimes one method won't work or another is just faster, depending on the quadratic equation given. So it is good to know different ways to solve quadratic equations so you will be prepared for any type of situation. After completing this tutorial, you will be a master at solving quadratic equations. Solving equations in general is a very essential part of Algebra. So I guess we better get to it. Tutorial Quadratic Equation Standard form: Where a does not equal 0.
