Answer:
discriminant = 0
The real root -2/3
Step-by-step explanation:
The formula for discriminant : b^2 - 4ac
12^2 (-4)×9×4 = 144 - 144 ➡ discriminant = 0 this means the roots is a repeated real number, which means there's only one solution
(3x + 2) × (3x + 2) = 0
3x+ 2 = 0
x = -2/3
217 is your answer because you start with the parthenogenesis
The next term is 1.4 larger than the one before it, so the appropriate choice is
_____
However, the description
also correctly describes the relationship between a1 and a2, for example. While this equation is technically correct, it is less useful to work with, so is probably not the expected answer.
