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)
