    -x ² + 2x - 2 = 0

    a = - 1

    b = 2

    c = - 2

    You can solve this by using the quadratic formula.

    x = (-b + / - √b² - 4ac) / (2a)

    x = (-2 + / - √2² - 4 (-1) (-2)) / (2 (-1)

    x = (-2 + / - √4 - 8) / - 2

    x = (-2 + / - √-4) / - 2

    x = (-2 + / - 2i) / - 2

    x = 1 + / - i

    x = 1 + i

    x = 1 - i
