X² - 4x + 3 = 0
x² + (-4x) + 3 = 0
x = <u>-(-4) +/- √((-4)² - 4(1)(3))</u>
                     2(1)
x = <u>4 +/- √(16 - 12)</u>
                 2
x = <u>4 +/- √(4)
</u>            2<u>
</u>x = <u>4 +/- 2
</u>           2<u>
</u>x = <u>4 + 2</u>      x = <u>4 - 2
</u>         2<u />                  2
