This week, I’ve learned how to find discriminants. To find discriminant, you take the b^2 – 4ac from the quadratic formula. The discriminant shows how many roots the quadratic equation is going to have. If its positive, it will have 2 roots, if its 0, it will have 1 root, and if its negative, there are no roots.

Using this method, its going to save more time finding which equation works.
