Step-by-step explanation:

Answer would be D You can have a rational discriminant for an irrational root, but you can also have rational discriminant for a rational root. So C is partially correct.
<span>All prime discriminants will result in an irrational root, but not all irrational roots have prime discriminants </span>
P: x + 2 = 9
x = 7 # Subtract 2 from both sides
E: q - 5 = 12
q = 17 # Add 5 to both sides
H: 6 + m = 27
m = 21 # Subtract 6 from both sides
Y: t - 14 = -3
t = 11 # Add 14 to both sides
J: u - 7.5 = 2.4
u = 9.9 # Add 7.5 to both sides
I: n + 7 = -20
n = -27 # Subtract 7 to both sides
G: d - 1 = -16
d = -15 # Add 1 to both sides
A: b - 40 = -25
b = 15 # Add 40 to both sides
M: 18 + w = 7
w = -11 # Subtract 18 from both sides
L: k + 8.3
k = 11.5 # Subtract 8.3 from both sides.
