Question 733309: What is the discriminant of x^2 + 6x + 9 = 0 and x^2 + 2x - 8 = 0. What can you conclude about the type of solutions in each case?
Answer by josmiceli(19441) (Show Source): You can put this solution on YOUR website!
The discriminant is in the
quadratic formula

When the discriminant is , there is
a single real solution ( called a double root )
--------------

The discriminant is positive, so there
are 2 real solutions

Here are plots of both equations:
