Answer:
the simplified expression = 7
and the exclude value =2.
Step-by-step explanation:
The rational expression is 
The rational function is undefined id denominator is zero.
Therefore, the excluded value is
x - 2 =0
x = 2
Now, we simplify the expression
Factor out GCF from numerator. The GCF is 7

Now, cancel out the common term in numerator and denominator

Therefore, the simplified expression is 7 and the exclude value is 2.
