After becoming a math teacher and math author, I notice that most students lack the basic skills in Math. This reason leads students to face many difficulties in learning Math not only in high school but also university. To help students in mastering their basic Math skills, we have worked through a workbook series called Algebra 1 Workbook for Dummies Series. This book series is designed to help students master their basics skill in Algebra 1.

Algebra 1 Workbook for Dummies: Quadratic Equations serves as a concise guide in quadratic equations. This book is written in detail about quadratic equations. We begin the first chapter of this book with the definition of quadratic equations. In this part, we want to make sure that the readers comprehend well about the definition before going deep into how to solve quadratic equations.

In the second chapter of this book, we listed many possible ways on how to solve a quadratic equation such as

• Factoring Method
• Completing Square Method
• Using Discriminant to Solve a Quadratic Equation
• Solve a Quadratic Equation in Case a+b+c=0 or a+c=b

Moreover, to dive into the higher level of Math, we also include the most famous theorem that is related to the sum and the product of the roots of equations. This theorem is known as Vieta's theorem. We decide to include this part in the third chapter of this book to help readers get more interests in quadratic equations.

The last chapter of this book is about the application of quadratic equations like how to solve a system of equations or a biquadratic equation by using a quadratic equation.

We hope this book serves as the best resource in learning Algebra 1, especially, quadratic equations.
