Quiz sobre equação do segundo grau.

by João
1

A equação do segundo grau tem a forma ax^2 + bx + c = 0, com a ≠ 0.

2

Quando Δ = 0, a equação tem uma única raiz real repetida.

3

Se Δ > 0, existem duas raízes reais distintas.

4

A raiz dupla ocorre apenas quando b = 0.

5

O discriminante Δ = b^2 - 4ac determina o número de soluções.

6

Se Δ < 0, as raízes são números inteiros.

7

O discriminante Δ é sempre positivo.

8

A fórmula de Bhaskara funciona apenas para equações com a = 1.

9

A soma das raízes de ax^2+bx+c=0 é igual a a.

10

A fórmula de Bhaskara é x = (-b ± sqrt(b^2 - 4ac)) / (2a).
