What are the solution(s) to the quadratic equation x2 – 25 = 0?
O x = 5 and x = -5
O X = 25 and x = -25
O x = 125 and x = -125
no real solution

O x = 5 and x = -5

Step-by-step explanation:

Given

X^2 - 25 = 0

Difference of two squares

That’s

x^2 - 5^2 = 0

Factorise the expression.

We have

(x - 5)(x + 5) = 0

Equate each parenthesis to 0

x - 5 = 0 Or x + 5 = 0

x = 5 OR x = -5
