Determine the solution set of x2 - 80 = 0
meriva

                                         x²  -  80  =  0
Add 80
to each side:                      x²          =  80

Square root
each side:                         x            =  √80

Look it up:                        x  =  + 8.944... (rounded)
                                 and
                                       x  =  - 8.944...  (rounded).
___________________________________

Here's a cleaner solution:

                                         x²  -  80  =  0
Add 80
to each side:                      x²          =  80

Square root
each side:                         x            =  √80

 But  80 = 16 · 5

 So     √80  =  √16 · √5

            √16 = 4, so            x  = 4 √5
