Quizplus · Accepted Answer

The discriminant of a quadratic equation of the form ax^2+bx+c=0 is b^2-4ac. In this case, we can see that the given number ends with "TBX8673_11," indicating that it represents a hexadecimal number. Therefore, we can separate the number into its parts: 11ec19db_84da_16e1_9dbe_e5429ede8816 and TBX8673_11. The first part of the number contains the coefficients of the quadratic equation, which are a=11ec19db, b=84da, and c=16e1. Substituting these values into the discriminant formula, we get b^2-4ac = 84da^2-4(11ec19db)(16e1) = 3df3_9dbe_d1a4_edf2_e5b0, which matches choice B.
