What is the discriminant of 9x² + 2 = 10x?

Solution:

9x² + 2 = 10x can be rewritten as

9x² - 10x + 2= 0

The above equation is a quadratic equation of the form ax² + bc + c = 0

The discriminant of which is defined by the expression:

Discriminant = b² - 4ac

a = 9

b = -10

c = 2

Discriminant = (-10)² - 4(9)(2) = 100 - 72 = 28

What is the discriminant of 9x² + 2 = 10x?

Summary:

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