4x² + 7x + 2 = 0
x = -7 +/- √(7² - 4(4)(2))
                  2(4)
x = -7 +/- √(49 - 32)
                   8
x = -7 +/- √(17)
               8
x = -7 +/- 4.123
              8
x = -7 + 4.123    x = -7 - 4.123
              8                        8
x = -2.877          x = -11.123
           8                          8
x = -0.359625    x = -1.390375
