X2*+36

It looks like you're referencing an expression that may need clarification. Are you trying to solve the equation \( x^2 + 36 = 0 \), or are you looking for something else regarding the expression \( x^2 + 36 \)?

If it's the equation \( x^2 + 36 = 0 \):

1. Start by isolating \( x^2 \): \[ x^2 = -36 \]

2. Then take the square root of both sides: \[ x = \pm \sqrt{-36} \]

3. Since the square root of a negative number involves imaginary numbers: \[ x = \pm 6i \]

So, the solutions to the equation \( x^2 + 36 = 0 \) are \( x = 6i \) and \( x = -6i \).

If you meant something different, please provide more context!
