To solve the equation
, we can start by isolating one of the square roots.First, let's isolate
by adding 5 to both sides of the equation:
Next, we can square both sides of the equation to eliminate the square roots:
Simplifying the equation, we get:
Now, let's isolate the square root term:
Simplifying further, we have:
Now, let's isolate the square root term again:
Simplifying, we get:
Now, let's isolate the square root term one more time:
Simplifying, we have:
Now, let's square both sides of the equation again to eliminate the square root:
Simplifying, we get:
Now, let's simplify the equation further:
Rearranging the terms, we have:
This is a quadratic equation, which can be solved using the quadratic formula:
In this case,
,
, and
. Plugging these values into the quadratic formula, we get:
