Find all "a" such that the equation sqrt(x) = a(x – 2) has a solution larger than 4

1) You're a little weak on the "show all steps" part. Please do that.
2) I'm buying this: -1<a<0
3) But this: 0<a<-1 ---- Are you SURE you want to go with that?
4) Did you square everything first? If so, did you notice that x > 0 before you did that?
 
So, "no", you did not notice that x > 0.
So, "yes", you ARE going with that incorrect inequality.
So, "no", you're not actually going to show any work.

" set it > 4" What motivated you to do this? A "solution" would require "set it = 0".

Give it another go.
