      The discriminant of 9x2 + 2 = 10x is 28

      General form of a quadratic equation => ax2 + bx + c = 0

      Formula for discriminant => b2 – 4ac

      Comparing general form, we get

      a = 9, b = -10, c = 2

      Discriminant => (-10)2 – 4(9)(2)

      => 100 – 72

      => 28

      The discriminant of 9x2 + 2 = 10x is 28
