Answer:
The value of the discriminant is 0
Step-by-step explanation:
The discriminant of a quadratic equation is calculated as thus:
b² - 4ac and it is represented by letter D.
Hence, D = b² - 4ac..
This discriminant can take either of 3 range of values.
1. D > 0. This implies that the discriminant has a value greater than 0 and this means that the root has 2 different real solutions
2. D = 0. This implies that the discriminant equals 0 and this means that the root has only 1 solution.
3. D < 0. This implies that the discriminant is less than 0 and this means that the root has 2 different complex solutions.
Hence, D = 0 is the correct answer to this question.

Answer:
Gabe worked 65, Abe worked 62 and Babe worked 69.
Step-by-step explanation:
Let Gabe = x
Therefore, Abe worked: x-3 and Babe worked x+4
So,
x+(x-3)+(x+4)=196
3*x+1=196
3*x=195
x=65
Then,
x-3= 62
x+4=69
