Homework Statement
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)
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.
