Answer:
A
Step-by-step explanation:
Because the 8 is independent while the 18 in dependent so 8 is x and 18 y I think
ax² + bx + c = 0
discriminant = b² - 4ac
----> x² + 7x + 12
---> Discriminant of this equation = 7² - 12.1.4 = 49 - 48 = 1 (Positive discriminant)
x = (-7 + 1)/(2.1) = -6/2 = -3
or
x = (-7 - 1)/(2.1) = -8/2 = -4
Therefore, this equation has two real solutions and has a positive discriminant.
The correct answer is B
