Answer 3

To solve the equation x^2 - 625 = 0, we can use the difference of squares formula. The difference of squares formula states that for any two numbers a and b, the expression a^2 - b^2 can be factored as (a + b)(a - b).

In this case, we have x^2 - 625 = 0. We can rewrite 625 as 25^2, so the equation becomes x^2 - 25^2 = 0. Now we can apply the difference of squares formula by factoring the left side of the equation:

(x + 25)(x - 25) = 0.

To find the values of x that satisfy the equation, we set each factor equal to zero and solve for x:

x + 25 = 0 or x - 25 = 0.

For x + 25 = 0, we subtract 25 from both sides to get x = -25.

For x - 25 = 0, we add 25 to both sides to get x = 25.

Therefore, the solutions to the equation x^2 - 625 = 0 are x = -25 and x = 25.

I hope this helps! Let me know if you have any further questions.
