Equations Involving a Variable Expression in the Denominator
0/0 doesn't equal 0! Begin this lesson plan by allowing the class to explore the concept of dividing by zero. The introduction allows for discovery and provides meaningful examples of dividing by zero. This understanding leads to solving...
Curated OER
Excluded Values
In this simplification of radicals worksheet, students solve 26 problems to find the values of the variable that should be excluded from answers because they will make the denominator equal zero.
