What is the discriminant of the polynomial?
2x^2+5x-8

Let's find the discriminant (D) of the given polynomial ~

Let's compare the given quadratic expression with general expression ~

we get ;

Now, use the following formula :

Therefore, discriminant of the given quadratic expression is 89

  n=   0.0000 - 0.3750 i  

  n=   0.0000 + 0.3750 i
