WebSince the highest degree term in a quadratic function is of the second degree, therefore it is also called the polynomial of degree 2. 1-to-1 Tutoring. Math Resources. Resources. ... The discriminant of a quadratic equation ax 2 + bx + c = 0 is given by b 2-4ac. This is used to determine the nature of the zeroes of a quadratic function. WebThe solution (s) to a quadratic equation can be calculated using the Quadratic Formula: The "±" means we need to do a plus AND a minus, so there are normally TWO solutions ! The blue part ( b2 - 4ac) is called the "discriminant", because it can "discriminate" between the possible types of answer: when it is negative we get complex solutions.
