WebFeb 17, 2024 · There are three main forms of quadratic equations. Our goals here are to determine which way the function opens and find the -coordinate of the vertex. Standard Form When the quadratic functions are in standard form, they generally look like this: If is positive, the function opens up; if it’s negative, the function opens down. 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.
