ax² + bx + c = 0, solved.
No matter the specific coefficients, ax² + bx + c = 0 is always solved by the same quadratic formula — that universality is exactly why it's one of the most memorized formulas in mathematics.
Two real roots mean the equation crosses zero twice, a repeated root means it just touches zero at one point, and complex roots mean the curve never touches zero at all.
