Question

Can sum one help me this is my last question

Answer 1

Answer:

Option B is correct.

the value of discriminant is, -7

Step-by-step explanation:

Given the equation: $x^2 + x +2 = 0$

To find the value of discriminant $b^2-4ac$

A quadratic equation is of the form $ax^2+bx+c = 0$ 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 = $b^2-4ac =(1)^2 -4(1)(2) =1 -8 = -7$

Therefore, the value of discriminant is, -7
