A number of things are to be found when solving quadratics.
Firstly, the x values, or zeros, need to be found to see where the function crosses the x-axis.
The y-intercept can be found when x is 0.
Whether it opens upwards or down, wide or narrow, domain or range, and much more.

It is finding the values of the variable that make the quadratic equation true.
That is what roots mean!

Because when your solving a quadratic equation your looking for x-intercepts which is where why equals 0 and x equals what ever the answer is.
By using the quadratic equation formula or by completing the square

The key challenges in efficiently solving the quadratic assignment problem include the high computational complexity, the large number of possible solutions to evaluate, and the difficulty in finding the optimal solution due to the non-linearity of the problem.
There are several methods for solving quadratic equations, although some apply only to specific quadratic equations of specific forms. The methods include:Use of the quadratic formulaCompleting the SquareFactoringIterative methodsguessing
you use the quadratic formula in math when the quadratic equation you are solving cannot be factored.

In math speak: Solving the equation means finding 'x' values that make the equation true. These 'x' values are called the roots of the quadratic.
By knowing how to use the quadratic equation formula.
You will apply them when solving quadratic equations in which the quadratic expression cannot be factorised.
