👉 The formula you're likely referring to is the quadratic equation, which is expressed as ax² + bx + c = 0. Here, 'a', 'b', and 'c' are constants (coefficients) that define the quadratic expression, while 'x' represents the variable. The equation describes a parabola when graphed on a coordinate plane, with 'a' determining the parabola's direction (upward if a > 0, downward if a < 0) and its width (larger absolute value of 'a' results in a narrower parabola). The solutions to the equation, known as roots or x-intercepts, are found by solving for 'x' using methods like factoring, completing the square, or applying the quadratic formula: x = (-b ± √(b² - 4ac)) / (2a). This formula is fundamental in algebra for solving equations where the highest power of the variable is two.
