Bravo !! Bravissimo !!! You just learned to write it using parentheses. Perfect !
---------------------------------------------------------------------------------------
= 0. (Did I write it correctly ?) --->
= x-10
Square both sides. You will get
5x = (x-10)^2, or
5x = x^2 - 20x + 100 ---> x^2 - 25x + 100 = 0 ---> = = = .
= 20. Check it !! It works.
= 5. Check it !! It doesn't work. This solution is EXTRANEOUS.
Answer. The only solution is x = 20.
Solved.
Do you see now how important is to write equations properly when posting to this site ?
Plot y =
------------------------
One NOTICE at the end:
What you wrote in your post was NOT exactly perfect.
EXACTLY perfect is this: (sqrt(5x)) -x + 10 = 0.
My next task is to teach you to say "Please" and "Thanks".
