Hi,

How do we find D if it is in the form ax^2 + bx = c?
D= Discrimatory
:
If discrimatory is the same thing as discriminant, then this is what you do.
Set the equation = to 0.
ax^2+bx-c=c-c
ax^2+bx-c=0 The discriminant is b^2-4ac
b^2-4(a)(-c)
highlight%28b%5E2%2B4ac%29
I hope it's the same thing.
Happy Calculating!!!
