The second degree equations or quadratic equations are equations in which the unknown appears at least once squared. They are studied in ESO and are usually one of the mathematical exercises that is most difficult for students to understand.
Second-degree equations have always had a bad name and that is why many students face them with fear and believe that they will not be able to solve them. Fortunately, today there are quite a few online resources that can help those who have problems with this type of mathematical exercises.
