Flashcards

Quadratic Equation Standard Form

The equation of a quadratic in standard form is $y = ax^2 + bx + c$, where a, b, and c are constants.

Arithmetic Progression Example

An arithmetic progression is a sequence of numbers with a common difference; for example, $3, 6, 12, 24, 48, ...$ is not arithmetic but has a ratio pattern.

Circle Area Formula

The area of a circle is calculated using the formula $A = \pi r^2$, where r is the radius of the circle.

Study Notes

Equations Quadratic

Le equation quadratic in forma standard es: ax^2 + bx + c = 0, dove a, b, e c es constantes.

Progression Arithmetic

Un exemple de un progression arithmetica es: 2, 5, 8, 11, 14, ..., dove cada termino es obtenite per addition de un valor constant (in questo caso, 3).
