By using the quadratic equation formula or by completing the square
The Quadratic Equation is useful because you can't factorevery equation, so you use the quadratic equation. Even though it doesn't seem fun it is still useful.
To find the roots (solutions) of a quadratic equation.
I suggest you use the quadratic formula.
Probably never.
Simply learn and use the quadratic equation formula.
By using the quadratic equation formula or by completing the square
you use the quadratic formula in math when the quadratic equation you are solving cannot be factored.
By knowing how to use the quadratic equation formula.
Because it's part of the quadratic equation formula in finding the roots of a quadratic equation.

You should always use the vertex and at least two points to graph each quadratic equation. A good choice for two points are the intercepts of the quadratic equation.
