1.4 Finding the zeros of a function - Zeros of polynomial function


By Mr. McLogan's Math Channel

In this video tutorial I show you how to find the zeros of the function. I do this by plugging in zero for the dependent variable, f(x), and then solving for the independent variable (x) using algebra. The methods I use to solve for x include completing the square, factoring, square root method, and quadratic formula.I show how to solve math problems online during a live classroom. 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 exaclty how to solve math problems step by step. The problems are done in real time and in front of a regular classroom.
