x²=4

x=±$\sqrt{4}$

Answer 3

To solve the equation -x^2 + 4 = 0, we can follow these steps:

Step 1: Move the constant term to the other side of the equation to isolate the squared term. -x^2 = -4

Step 2: Divide both sides by -1 to get rid of the negative sign in front of the squared term. x^2 = 4

Step 3: Take the square root of both sides to solve for x. x = ±√4

Step 4: Simplify the square root expressions. x = ±2

So, the solutions for the equation are x = 2 and x = -2.
