Question

2.3.3 How can we determine that the expressions are equivalent?

Answer 1

Two expressions are equivalent if they can be simplified to the same third expression or if one of the expressions can be written like the other. Moreover, one can also determine if two expressions are equivalent when values are substituted in for the variable and both arrive at the same answer. We can use models to determine if two expressions are equivalent.
