Answer:
the discriminant of a given quadratic equation is 120. describe it's roots.
2 and -9.
The roots for this equation are 2 and -9. This is because the discriminant is 120 which sets up a perfect square for the roots to be on opposite sides of each other. The diagonal of the square is 9 which tells us that there will be two solutions, one with a plus sign and one with a minus sign. So if we get an answer such as B+ we know that it has to be either 2 or -9, both having 90 in them (the 90 being from the discriminant).
