The quadratic formula can be derived by used a method called completing the square. It's like using algebra to solve for x. The process is explained the related link "Derivation of Quadratic Formula".
That's related to the fact that, for example, x squared is the same as (-x) squared. Note that any equation of the form "x squared + bx + c = 0", with constants a, b, and c can be rewritten as "(x - d) squared + f = 0", for possibly different constants d and f.
A related equation is a set of equations that all communicate the same relationship between three values, but in different ways. Example: a+b=c a=c-b b=c-a
8 divided by 4 = 2
They are different ways to represent the answers of an equation
