Sagot :

Panoyinidn
4x² + 3x + 5 = 0
x = -3 +/- √(3² - 4(4)(5))
                   2(4)
x = -3 +/- √(9 - 80)
                 8
x = -3 +/- √(-71)
                8
x = -3 +/- √(71 × (-1))
                   8
x = -3 +/- √(71) × √(-1)
                    8
x = -3 +/- 8.43i
              8
x = -0.375 +/- 1.05375i
x = -0.375 + 1.05375i      x = -0.375 - 1.05375i
