It just stands for the coefficients (integers) in front of your terms.
So if you have an equation x² - 3x + 8,
. a is the coefficient of your x² term -- in this case a = 1
. b is the coefficient of your x term -- in this case b = -3
. c is the coefficient of the non-x term -- in this case c = 8
The quadratic formula assumes your equation is in the format of a² + bx + c; that's where the letters come from and that's how you determine what they stand for.
Hope that helped!

The standard form of a quadratic is a*x^2+b*x+c=0; it's the same a, b and c in the solution formula.

Quadratic formula: a,b & c are the co-efficient of x^2, x,and constant respectively....
ax^2 + bx + c =0

using the formula ax^2+bx+c, the a is to coefficient for the term that is squared, the b for the term raised to the first power and the c is the final term

in y = 3x² + 4x + 5
the a is the 3, the b is the 4 and the c is the 5

to understand you need to know that y = x² is the "standard" graph of the parabola...[x & y intercept at the origin]......y = a x² then has "a" determining both the direction of the opening and the "narrowness" of the graph...|a| < 1 is a wider graph, |a|>1 is a narrower graph....y = a x² + bx takes the previous graph and moves it both right/left and up/down so that x = 0 and x = -b/a are x axis intercepts { and the vertex is now at x = -b / 2a....on a line exactly between the zeros}....[y intercept is still the origin].....y = a x² + bx + c takes this last graph and moves it up/down so the point (0,c) is now the y intercept....{ x intercepts..if they exist...have been changed}

a is the coefficient of the square term,b the coefficient of the middle term and c the constant term
ax^2+bx+c=o

they are just letters you can name them as you like, you just have to remember that
(hypotenuse, the longest side) on square = (1st smaller side) on square + (2nd smaller side) on square
