The answer is:  

Example Question #4277 : Algebra Ii

Solve:  

Possible Answers:

Correct answer:

Explanation:

Square both sides.

We will need to simplify the left side using the FOIL method.

A radical multiplied by itself becomes what's inside the radical.

The expression becomes:

Combine like-terms and rewrite the equation.

Isolate the radical by adding  and subtract 17 on both sides.  Then divide by two on both sides.

The radicals can be combined as one whole using the FOIL method.

Square both sides.

The  terms will cancel by subtracting the term on both side, and we can solve for .

Add  on both sides.

Multiply by four on both sides to eliminate the fraction.

Solve for x.
