1 6-5 The Quadratic Formula and the Discriminant ObjectivesStudents will be able to:Solve quadratic equations by using the Quadratic FormulaUse the discriminant to determine the number and type of roots of a quadratic equation
2 Using the quadratic formula is yet another way to solve quadratic equations. What is the quadratic formula? Perhaps it’s best explained through song…Quadratic FormulaThe formulaUse the formula below to find the solutions of a quadratic equation in the form
3 So how do we use the quadratic formula So how do we use the quadratic formula? Solve the following equation using the quadratic formula:
4 Solve each equation by using the quadratic formula. 1)
14 There are times when you will be given a quadratic equation and be asked to solve. It is then up to you to determine which method you would like to use to solve. It is important to be able to distinguish between the different methods, and to know which methods will work all the time, and which methods will only work sometimes.
