Answer:
The value of discriminant is -7.
Step-by-step explanation:
The given equation is,
x^2+x+2=0x
2
+x+2=0
The standard form of the quadratic equation is,
ax^2+bx+c=0ax
2
+bx+c=0
By comparing the given equation with the standard equation we get,
a = 1, b = 1 and c = 2.
The Formula for discriminant is,
D=b^2-4acD=b
2
−4ac
Substitute a = 1, b = 1 and c = 2,
D=1^2-4(1)(2)D=1
2
−4(1)(2)
D=1-8D=1−8
D=-7D=−7
Therefore, the -7 is the value of the discriminant.
