The discriminant of 9x^{2} + 2 = 10x is **28**

General form of a quadratic equation => ax^{2} + bx + c = 0

Formula for discriminant => b^{2} – 4ac

Comparing general form, we get

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

Discriminant => (-10)^{2} – 4(9)(2)

=> 100 – 72

=> 28

The discriminant of 9x^{2} + 2 = 10x is 28
