Question

Can sum one help me this is my last question

Answer 1

Option B is correct.

the value of discriminant is, -7

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
