One solution of x^2-25=0 is 5 what is the other solution

Add 25 to both sides:



x^2 = 25


Square root both sides.


When you square root a perfect square, you will get a plus/minus result:



√(25) = \pm 5



x = \pm 5


\boxed{x = -5} \land \boxed{x = 5}


The other solution to this answer is x = -5.
