- represents the value of the vertex.
For example:
In the function
The vertex of the parabola is:
Note-
The vertex formula is structured such that there is always a – before the , meaning vertex, but this does not necessarily mean that the vertex is negative.
If the parabola has a negative vertex, a will appear before the in the formula because times equals .

Sometimes we encounter quadratic equations that are missing terms such as or and quadratic equations with denominators.
Quadratic equations with missing terms are quadratic equations where or are equal to .

Sometimes we encounter quadratic equations with a fraction (numerator and denominator). To read the function more accurately, we need to get rid of the fraction.
To solve quadratic equations with denominators-
find the common denominator, multiply each term, and obtain an equation without a fraction. Then solve it completely normally and find the solutions.
