Respuesta :
x^2 - 25 = 0
Add both sides by 25
x^2 = 25
Take the positive and negative square root.
x = 5
OR
x = -5
Have an awesome day! :)

Answer:
there are two solutions are x = (+5) and x = (-5)
Step-by-step explanation:
The given quadratic equation is x² - 25 = 0
Now we can get the solutions of this equation by zero factors.
[ since (a² - b²) = ( a-b ) ( a+b ) ]
so x² - 25 = (x-5) (x+5)
( x-5 ) = 0 ⇒ x = 5
or x + 5 = 0 ⇒ x = -5
Therefore, there are two solutions are x = (+5) and x = (-5)
