Respuesta :
Yes. You can solve in the usual way.
Take the square root:
... x-7 = ±√0 = 0
Add 7:
... x = 7
_____
There is one distinct real solution (with multiplicity 2).
yes that does have a solution if u replace x with 7 your solution will be 0, because
(7-7)^2=0
(0)^2=0
0=0
(7-7)^2=0
(0)^2=0
0=0
