To solve the equation
, we need to isolate the square root term and then solve for
.First, let's rewrite the equation:
Add
to both sides to isolate the square root term:
Next, square both sides to eliminate the square root:
Rearrange the equation to standard quadratic form:
Now, we can solve this quadratic equation using the quadratic formula
, where
,
, and
.Calculate the discriminant:
Now, apply the quadratic formula:
This gives us two solutions:
We need to check these solutions in the original equation to ensure they are valid.For
:
This is a valid solution.For
:
This does not satisfy the original equation.Therefore, the only valid solution is
.So, the correct choice is:A. The solution set is
