Answer 2

To clarify the equation you provided:

-1 * x^2 + 20 = 0

It seems like you have a quadratic equation. To solve for the value of x, we can follow these steps:

Step 1: Move the constant term to the right side of the equation:

-1 * x^2 = -20

Step 2: Divide both sides by -1 to isolate x^2:

x^2 = 20

Step 3: Take the square root of both sides:

x = ±√20

Step 4: Simplify the square root:

x ≈ ±4.47

So, the solutions for the equation are approximately x = 4.47 and x = -4.47.
