radical equation  no solution right?
posted by Nik H. on .
radical sign (w + 5) = 2
In all my problems there are a letter variable on the end
example:
radical sign (u + 30) = u
I then square both sides, drop the radical sign then
(u+6)(u5)=0
then check to see if they are both true
I guess my question is this is a no solution problem right?

sqrt (36)=6 checks, so u=6 is ok
sqrt (25)=5 is ok
Both are solutions. I am wondering why you thought no solution.
