Finding Roots of a Quadratic Equation
In this lesson, you will learn how to find the roots of a quadratic equation, which are the same as the x-intercepts. The first step is to set the equation equal to 0, then use the quadratic formula to solve for a, b, and c. Next, you factor the equation and use the zero product property to find the roots. Make sure to set the equation equal to 0 to avoid common mistakes.
How to find the roots of a quadratic equation
I show how to solve math problems online during live instruction in class. This is my way of providing free tutoring for the students in my class and for students anywhere in the world. Every video is a short clip that shows exactly how to solve math problems step by step. The problems are done in real time and in front of a regular classroom. These videos are intended to help you learn how to solve math problems, review how to solve a math problems, study for a test, or finish your homework. I post all of my videos on YouTube, but if you are looking for other ways to interact with me and my videos you can follow me on the following pages through My Blog, Twitter, or Facebook.
- How should a quadratic equation be written before we can find its roots?
- Following the example that was explained, identify the values of a, b and c in x² - 3x - 5 = 0
- What must you remember to do in each step of your solution?
- After you have factorised it, what is the next step/
- What will be the roots of the equation?
