Answer:x = 2 & - 2Step-by-step explanation:We have to find the value of x from the given equation. x²-4=0 is a quadratic equation, so it will have two values. Step: Write the equation in simplest form. x²-4=0Step: Solve the problem by spiltting method.x² - 4 = 0x² - (2)² = 0Step: Solve the problem with using algebraic formula. x² - 2² = 0 (x - 2)(x + 2) = 0 Step : We have used a²-b² to solve the problem. (x - 2)(x + 2) = 0 (x - 2)(x + 2) = 0(x - 2)=0 or (x + 2) = 0x = 2 & - 2Therefore, the possible values of x are 2 & - 2.
