Answer:
Step-by-step explanation:
This is a quadratic equation in standard form written as ax² + bx + c = 0, where a = 1, b = 0, and c = -25.
To solve for x, we can use the quadratic formula:
x = (-b ± sqrt(b² - 4ac)) / 2a
Plugging in the values, we get:
x = [-(0) ± sqrt((0)² - 4(1)(-25))] / 2(1)
x = ±sqrt(100) / 2
x = ±10 / 2
x = ±5
Therefore, the solutions to the equation x² - 25 = 0 are x = 5 and x = -5.#Mark me as brainliest
