8.2 When and Why Do We Write Quadratic Equations?
A strategy such as this might be difficult to use when the solutions are harder to find
Practice this chapterA strategy such as this might be difficult to use when the solutions are harder to find You set quadratic equations equal to zero when possible to find solutions in context
A quadratic equation that has been set equal to zero provides more opportunities for how to solve it. By developing a better understanding of quadratic equations, you also better understand the context of a real-world situation
Be able to recognize the factored form of a quadratic expression and know when it can be useful for solving problems; use a graph to find the solutions to a quadratic equation but also know its limitations.
