quadratic formula
[quadratic formula|quadratic formula] is a method that generates the solutions to a quadratic equation and reveals the nature of the solutions through the discriminant, b² − 4ac.
Definition
quadratic formula is a method that generates the solutions to a quadratic equation and reveals the nature of the solutions through the discriminant, b² − 4ac. Although it works on any quadratic equation in standard form, it is easy to make errors in substituting the values.
Mechanism
quadratic formula solves quadratic equations by using the quadratic formula to find solutions for variables in second-degree polynomials.
Effects
quadratic formula can produce approximate solutions when the square root does not simplify nicely, as demonstrated by the calculation of t ≈ 5.458 seconds for the ball hitting the ground. The formula's application results in two potential solutions, but only one is within the reasonable domain of the model.
