# What is the discriminant of -8x^2+4x−1 and what does that mean?

##### 1 Answer

**discriminant** =

**It means that the polynomial has no real solutions**

#### Explanation:

the discriminant is a function of the coefficients of a polynomial equation whose value **gives information** about the **roots** of the polynomial

consider a function

in order to find the values of

where **discriminant**

if

**two** real solutions

**one** real solution

**no** real solution

so in the equation

by substituting in the discriminant formula with

so the functions will have **no real solutions**

(but it will have imaginary solutions)
