I'm going to look at a very similar expression Excluded values are values of x that result in the expression producing something which is not a real number. In my expression a value of x = 2 makes the denominators equal to zero and hence the expression evaluates to something that is not a real number. For any other value of x the two sides of the equation yield real numbers. Thus the only excluded value is x = 2. To solve the equation I would multiply both values by x  2 to get
which on simplification becomes
But for x = 2 is excluded so the equation has no solution. Sometimes we say that x = 2 is an extraneous solution. This is why it's important to verify your answer when you solve an algebraic equation. If you missed the fact that x = 2 is an excluded value and solved the equation as I did you might think that x = 2 is a solution. An attempt at verification by substitution of x = 2 into the original equation shows that x = 2 is not a solution. Now try your problem,
