Question 1105834
Discriminant k^2+12k+20 ?
I do not believe so. 
Given the discriminant of k^2+12k+20, ... but then the discriminant IS NOT GIVEN.


How about, USE the discriminant of k^2+12k+20  to find how many zeros this expression has?


YOU find the discriminant!   You do that!
ax^2+bx+c will have discriminant  b^2-4ac.



If discriminant is positive, then there are two real zeros.
If discriminant is 0, then there is one real zero.
If the discriminant is negative, then there are two COMPLEX zeros or BOTH zeros are NOT real.  No real zeros.

Your intermediate algebra book should have a lesson or some instruction about this.
