Exploring Zeros of Quadratic Functions: Methods and Techniques

This guide covers essential techniques for finding the zeros of quadratic functions and models. Learn how to identify zeros through factoring and using the quadratic formula. The process involves setting the equation to zero, factoring where possible, and substituting values into the formula. It's important to recognize that sometimes there may be no real solutions. Additionally, you may need substitution for certain problems. Dive into this topic to enhance your understanding of quadratic functions and their applications!
