-12x² + 11x - 3 = 0
x = <u>-(11) +/- √((11)² - 4(-12)(-3))</u>
                        2(-12)
x = <u>-11 +/- √(121 - 144)</u>
                   -24
x = <u>-11 +/- √(-23)
</u>              -24
x = <u>-11 +/- i√(23)</u>
             -24
x = <u>-11 + i√(23</u>)                x = <u>-11 - i√(23)</u>
            -24                                   -24
x = ¹¹/₂₄ - 0.0416√(23)      x = ¹¹/₂₄ + 0.0416√(23)
