Answer 2

To solve the equation x² - 9 = 0, we can factor the equation as the difference of squares:

(x - 3)(x + 3) = 0

Now, we can set each factor equal to zero and solve for x:

x - 3 = 0 or x + 3 = 0

Solving the first equation, we add 3 to both sides:

x = 3

Solving the second equation, we subtract 3 from both sides:

x = -3

Therefore, the solutions to the equation x² - 9 = 0 are x = 3 and x = -3.
