-x² + 8x - 6 = 0
x = -(8) +/- √((8)² - 4(-1)(-6))
                     2(-1)
x = -8 +/- √(64 - 20)
                 -2
x = -8 +/- √(44)
              -2
x = -8 +/- 2√(11)
              -2
x = -8 + 2√(11)         x = -8 - 2√(11)
             -2                            -2
x = 4 - √(11)             x = -8 + √(11)
