1 Answer
Rewrite this equation as a quadratic and proceed to solve for
Explanation:
Before doing anything else, isolate the radical term on one side of the equation.
To do that, add
Now square both sides of the equation to get rid of the radical term
Move all your terms to one side of the equation to get
Use the quadratic formula to determine the two solutions ofr this equation
Check to see if both solutions satisfy the original equation. Since both solutions are positive, the radical term will always be positive, so all you really need to check is whether or not the right side of the equation is positive as well.
