Quadratic Equations and Applications Quiz

Solving for the roots of a quadratic equation using the formula x = (-b ± √(b² - 4ac)) / 2a

Roots' sum is given by -b/a, where b is the coefficient of the linear term

A technique involving transforming a quadratic equation to a perfect square trinomial to facilitate solving

Utilizes the vertex coordinates to identify the maximum or minimum value of the quadratic function

Vertical line passing through the vertex, ensuring symmetry in the parabola's shape

Discriminant indicates the nature of roots; positive for two real roots, zero for one real root, and negative for complex roots

A form highlighting the vertex (h, k) of the parabola with a as the leading coefficient

Implies the presence of complex roots, as the square root of a negative discriminant is imaginary

Parabola faces upwards, with the vertex representing the minimum value of the quadratic function

Ensures the existence of real and equal roots, avoiding division by zero in the quadratic formula

Affirms that the roots may involve imaginary numbers, particularly when the discriminant is negative

Key value used to determine the nature of the roots; discriminant greater than 0 signifies real roots

Canonical form encompassing the quadratic terms and coefficients

Negative 'a' values ensure roots with opposite signs, leading to a parabola crossing the x-axis

A perfect square trinomial results in a single, repeated real root
