Algebra 2 help: Solve. Check for extraneous solutions. 5√x + 7 = 8
I know I have to isolate 5√x to get 5√x = 1, but where do I go from there?
Divide 5 on both sides..
Alright; I now have √x = 1/5 Though, the final answer (I have the key) is 1/25. Is there something else that I'm missing?
Now you should take square on both sides to get rid of sqrt on left.
Oh, alright. I got it, thank you! :)
