(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

sqrt(2x+4) = sqrt(6x+1) - 1

I Need to solve for x, but cannot seem to get the same answer as the text. (Ans. x= 5/2)

3. The attempt at a solution

sqrt(2x+4) - sqrt(6x+1) = -1

square both sides

(2x+4) - (6x+1) = 1

-4x-3=1

-4x=4

x=-1 ??

I know I must be doing something wrong, it has been a while since I have done this sort of problem.

Thank you for your time.
