Answer:
Step-by-step explanation:
the disc. is the part under the root in the general formula
which is equal b^2 - 4 x a x c
in this equation a = 1 " coefficient of x^2"
b = 0 "coefficient of x which isn't found here "
c = 12 " the absolute "
[tex]0^{2} - 4[/tex]×[tex]1[/tex]×[tex]12[/tex] = -4×12 = something i don't have a calculator
but it will be negative so the roots will be complex and unreal
