Exercises 5
When algebraic equations contain a symbol whose value has not yet been determined, we use analysis to determine
whether:
a. The equation is true for all the possible values of the variable(s), or
b. The equation is true for a certain set of the possible value(s) of the variable(s), or
C. The equation is never true for any of the possible values of the variable(s).
For each of the three cases, write an algebraic equation that would be correctly described by that case. Use only the
variable, x, where x represents a real number.
