Remember, division by zero is NOT defined. So this means that ANY values that make the denominator of equal to zero will also make the expression undefined.
Start with the given expression.
Set the denominator equal to zero.
Add to both sides.
Combine like terms on the right side.
Divide both sides by to isolate .
Reduce.
So when , the expression is equal to zero.
In turn, when the denominator of is equal to zero.
So if this makes the expression undefined.
