What is the excluded value for the rational expression of two b over b squared minus eight?
:

:
One of the hard and fast rules is, an expression cannot have division by 0
or another words, the denominator cannot = 0
The value that causes the denominator to be 0 is an excluded value
:
To find the excluded value of this expression
b^2 - 8 = 0
b^2 = 8
b = +
and
b = -
are the excluded values
