Algebra (Class 36)
Overview
§5-12 (p.231) Solving Equations by Factoring (Using the Zero Product Property)
A Visual Approach to Functions
Today we begin a more focused study of linear functions. We also continue to improve on our ability to solve polynomial equations by factoring.
Key Attitudes
Mathematics is about reasoning.
Key Ideas
The slope of a graph of distance compared to time can be used to infer the rate, in this case speed, of the object whose data is being graphed.
Key Skills
Labeling a graph properly with then names of the variables, the units in which the variables are being measured, the scale of the axes, and the title of the graph.
Factoring second degree trinomial equations.
Applying the Zero Product Property.
Clearly writing the steps for solving equations.
