<u>ANSWER</u>
Extraneous solution: x=6
Real solution: x=11
<u>EXPLANATION</u>
The given expression is
Add -8 to both sides:
Square both sides.
We expand the to get
Write in standard quadratic form.
Factor to get:
We check for extraneous solutions by substituting each value of x into the original equation.
When x=6
Hence x=6 is an extraneous solution.
When x=11
This statement is true.
Hence x=11 is the only solution.
