The result of simplifying an algebraic expression
The result could be a value of an expression and the proof is as follows:
Let the expression be:
[tex]z = 3x^2 - xy + 2xy -xy - 3x^2 + 2[/tex]
When simplified (collect like terms)
[tex]z = 3x^2 - 3x^2- xy + 2xy -xy + 2[/tex]
[tex]z = 0- xy + 2xy -xy + 2[/tex]
[tex]z = xy -xy + 2[/tex]
[tex]z = 2[/tex]
In this case, the result is 2 (a value).
In another case:
[tex]z = 3x^2 - xy + 2xy + 2[/tex]
When simplified (collect like terms)
[tex]z = 3x^2 + xy + 2[/tex]
Here, the result is an algrbraic expression.
