What is the value of b² - 4ac for the following equation? 5x² + 7x = 6

Solution:

A discriminant of a quadratic equation is a function of the coefficients of the polynomials.

D = b² - 4ac

The given equation is 5x² + 7x = 6

a is the coefficient of x²

b is the coefficient of x

c is the constant term

Substituting the values

D = 72 - 4 × 5 × (-6)

D = 49 + 120

D = 169

Therefore, the value is 169.

What is the value of b² - 4ac for the following equation? 5x² + 7x = 6

Summary:

The value of b² - 4ac for the following equation 5x² + 7x = 6 is 169.
