The Quadratic Formula uses the "a", "b", and "c" from "ax2 + bx + c", where "a", "b", and "c" are just numbers; they are the "numerical coefficients" of the quadratic equation they've given you to solve.

The Quadratic Formula is derived from the process of completing the square, and is formally stated as:
The Quadratic Formula: For ax2 + bx + c = 0, the values of x which are the solutions of the equation are given by:
x = \dfrac{-b \pm\sqrt{b^2 - 4ac\,}}{2a}x=2a−b±b2−4ac

Step-by-step explanation:
In mathematics, a quadratic is a
type of problem that deals with a
variable multiplied by itself — an
operation known as squaring.
This language derives from the
area of a square being its side
length multiplied by itself. The
word "quadratic" comes from
quadratum, the Latin word for
square.
Quadratic equations characterize
a great number of phenomena in
the real world, such as where a
rocket ship will land, how much
to charge for a product or how
long it will take a person to row
up and down a river. Because of
their wide variety of
applications, quadratics have
profound historical importance
and were foundational to the
history of algebra.
