Ax^2 + bx + c = 0
x^2 + x + 2 = 0
a = 1
b = 1
c = 2
b^2 - 4ac
1^2 - 4(1)(2)
= 1 - 8
= -7
The value of the discriminant is -7.
We are asked to find the length of

, which measures

. Using the segment addition postulate, we can add the two given expressions for

and

and make it equal to the expression for

.





We've found the value of

, but we aren't done yet. We need to plug in the value we got for

into the expression for

, which is

. Therefore,

. Hope this helped and have a great day!

Answer:
D. -11/12
Step-by-step explanation:
Slope Formula: 
Simply plug in our coordinates:
m = (4 - 15)/(0 + 12)
m = -11/12
