Question 534427
Reduce the rational expression to lowest terms. If it is already in lowest terms, enter the expression in the answer box. Also, specify any restrictions on the variable. 


-8
-------
4x - 20


-8
-------- {factored 4 out of bottom}
4(x - 5)


-2
------- {cancelled -8 and 4}
x - 5


Restrictions on variable would be those that make the denominator equal to 0.
Variable restriction: x cannot be equal to 5 {that would make denominator 0}
