Answer:
Option B is correct.
the value of discriminant is, -7
Step-by-step explanation:
Given the equation: [tex]x^2 + x +2 = 0[/tex]
To find the value of discriminant [tex]b^2-4ac[/tex]
A quadratic equation is of the form [tex]ax^2+bx+c = 0[/tex] where a, b and c are coefficient of the equation.
On comparing with given equation we have;
a = 1 , b = 1 and c = 2
then;
Discriminant = [tex]b^2-4ac =(1)^2 -4(1)(2) =1 -8 = -7[/tex]
Therefore, the value of discriminant is, -7
