# What is the value of b^{2} - 4ac for the following equation? 5x^{2} + 7x = 6

**Solution:**

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

D = b^{2} - 4ac

The given equation is 5x^{2} + 7x = 6

a is the coefficient of x^{2}

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 b^{2} - 4ac for the following equation? 5x^{2} + 7x = 6

**Summary:**

The value of b^{2} - 4ac for the following equation 5x^{2} + 7x = 6 is 169.
