How many solutions does the equation x^2 - 4 = 0 have?

  1. 0

  2. 1

  3. 2

  4. 3

The correct answer is: 2

The equation x^2 - 4 = 0, also written as x^2 = 4, can be solved by taking the square root of both sides. This gives us two possible solutions x = 2 and x = -2. Therefore, this equation has 2 solutions. Option A is incorrect because the two solutions, x = 2 and x = -2, cannot be "zero." Option B is incorrect because, as previously mentioned, there are two solutions to this equation. Option D is incorrect because it is a multiple choice question and there cannot be 3 solutions for a quadratic equation. The two solutions are the result of taking the square root of both sides, not because of any other factor in the equation.
