For which values of the real coefficient
For which values of the real coefficient a have the equation x ^ 2 + ax + 10 = 0
A) two real roots
B) a real, so-called double root
C) no real roots
Know that the discriminator should be positive for two real roots and 0 to be a real double root, as well as negative for no real roots, but do not understand how to calculate it?

Welcome to the study emergency ward!
Um... but the question doesnt ask you to calculate it, so you dont have to. You can only have an expression for the roots since "a" is unknown.
Btw, its called discriminant, not discriminator.
