This week I learned how to find the discriminant. To find the discriminant, you take the b² – 4ac 

from the original quadratic formula, the discriminant is how you can find out how many roots the quadratic equation is going to have. If the discriminant above 0 it will have 2 roots, if the discriminant is 0, you will have 1 root, and if the discriminant is negative, there are no roots.
