This shows the whole quadratic function, not just the doubled up solution. If you were trying to factor it as an equation, then you are correct in that f(x) 6(x-10)(x-10) or f(x) 6 (x-10)2. ***Highlighted path on the cover photo is intentionally incorrect to protect the answer key. Since you are finding solutions, not the equation, the 6 does not have any meaning because as Sal did in the beginning, 0/6 0. As students find the answers to the problem, they follow the correct answer pathway and shade it in as they go, making for very easy grading in the end! Quadratics by factoring (intro) Solving quadratics by factoring: leading coefficient 1. This includes equations with coefficients of 1, and greater than 1. Lesson 5: Solving quadratics by factoring. The only way to get a product equal to zero is to multiply by zero itself. The Zero Product Property says that if the product of two quantities is zero, it must be that at least one of the quantities is zero. Solving Quadratic Equations by Factoring Date Period Solve each equation by factoring. We will first solve some quadratic equations by using the Zero Product Property. This is generally true when the roots, or answers, are not rational numbers. Write the equation in form ax + bx + c 0. Solve Quadratic Equations Using the Zero Product Property. Many quadratic equations cannot be solved by factoring. In this fun maze worksheet, students practice solving quadratic equations by factoring. The following steps will be useful to factor a quadratic equation. Students solve quadratic equations and match them to the answers to reveal the answer to a riddle, so students will know right away if they've simplified correctly! The file contains the student worksheet and teacher answer key. A fun way for students to practice solving quadratic equations by factoring! When you use the Principle of Zero Products to solve a quadratic equation, you need to make sure that the equation is equal to zero.
