Solving equations is the central theme of algebra. All skills learned lead eventually to the ability to solve equations and simplify the solutions. In previous chapters we have solved equations of the first degree. You now have the necessary skills to solve equations of the second degree, which are known as quadratic equations. Upon completing this section you should be able to: Identify a quadratic equation. Place a quadratic equation in standard form. Solve a quadratic equation by factoring. A quadratic equation is a polynomial equation that contains the second degree, but no higher degree, of the variable. All quadratic equations can be put in standard form, and any equation that can be put in standard form is a quadratic equation. In other words, the standard form represents all quadratic equations. This theorem is proved in most college algebra books. An important theorem, which cannot be proved at the level of this text, states "Every polynomial equation of degree n has exactly n roots. It is possible that the two solutions are equal. A quadratic equation will have two solutions because it is of degree two.

Our first step is to get the equation in standard form. Upon completing this section you should be able to: Identify a perfect square trinomial.

The calculator will solve the quadratic equation step by step either by completing the square or using the quadratic formula. It will find both the real and the imaginary complex roots. Related calculator: Discriminant Calculator. Enter a quadratic equation:. Welcome to the ultimate online Quadratic Equation Calculator!

In other words, if the product of two factors is zero, then at least one of the factors is zero. In other words, the first and third terms are perfect squares. Again, this quadratic can be factored. We now have. Descriptive Statistics. We leave the check for you! Use the Discriminant to Predict the Number and Type of Solutions of a Quadratic Equation When we solved the quadratic equations in the previous examples, sometimes we got two real solutions, one real solution, and sometimes two complex solutions. The physical restrictions within the problem can eliminate one or both of the solutions. Our first step is to get the equation in standard form. Rationalize Denominator. Add - 3 to both sides. The Quadratic Equation Calculator is an online tool designed to solve quadratic equations. Write the Quadratic Formula.

Wolfram Alpha can apply the quadratic formula to solve equations coercible into the form. In doing so, Wolfram Alpha finds both the real and complex roots of these equations. It can also utilize other methods helpful to solving quadratic equations, such as completing the square, factoring and graphing.

Access these online resources for additional instruction and practice with using the Quadratic Formula. Note that smaller values of a form a wider parabolic curve, and larger values of a form a thinner parabola. Notice here the two solutions are equal. Solve Quadratic Equations Using the Quadratic Formula When we solved quadratic equations in the last section by completing the square, we took the same steps every time. Write as two solutions. The left side is a perfect square, factor it. Isolate the variable terms on one side. Example 1 If the length of a rectangle is 1 unit more than twice the width, and the area is 55 square units, find the length and width. Coefficients may be either integers 10 , decimal numbers Solve by completing the square. Write the equation in standard form by adding 5 to each side. The Quadratic Equation Calculator is an online tool designed to solve quadratic equations. Again, checking the solutions will assure you that you did not make an error in solving the equation. It looks complex, but we are following the same exact rules as before.
