Simplify the following rational expression and express in expanded form.

The solution for given expression is

Given that rational expression is:

Taking "4" as common term from denominator,

 ------- eqn 1

Let us use a algebraic identity which is as follows:

So, can be expressed as:

Substitute the above equation in eqn 1,

Cancelling (z + 2y) in numerator and denominator

Thus the solution for given expression is

domain is all the x values included in the

0 ≤ x ≤ 2

range is all the y values of the graph

-2 ≤ y ≤ 2

***keep in mind that there are different ways to show domain and range

hope this !
