b%5E2-4ac is equal to D because this is the discriminant.


D=b%5E2-4ac Start with the discriminant formula.


D=%286%29%5E2-4%282%29%283%29 Plug in a=2, b=6, and c=3


D=36-4%282%29%283%29 Square 6 to get 36


D=36-24 Multiply 4%282%29%283%29 to get %288%29%283%29=24


D=12 Subtract 24 from 36 to get 12


So the discriminant is D=12
