Question

Sabendo os coeficientes, escreva a equação do 2° grau

A) b = 0 c = 1 a = -2
B) a = 2 c = 4 b = 1
C) a = -2 b = 1 c = 0
D) a = 1 c = 2 b = 5
E) b = 0 c = 3 a = -6
F) a = -1 b = 0 c = 0
G) a = 2 c = 5 b = 3

Answer 1

$- 2 {x}^{2} + 1 = 0$
$2 {x}^{2} + x + 4 = 0$
$- 2 {x}^{2} + x = 0$
${x}^{2} + 5x + 2 = 0$
$- 6 {x}^{2} + 3 = 0$
$- {x}^{2} = 0$
$2 {x}^{2} + 3x + 5=0$

Answer 2

Resposta:

Explicação passo-a-passo:

a.x^2 + b.x + c = 0

A) b = 0 c = 1 a = -2

a = 2; b = 0; c = 1

-2x^2 + 1 = 0

B) a = 2 c = 4 b = 1

a = 2; b = 1; c = 4

2x^2 + x + 4 = 0

C) a = -2 b = 1 c = 0

-2x^2 + x = 0

D) a = 1 c = 2 b = 5

a = 1; b = 5; c = 2

x^2 + 5x + 2 = 0

E) b = 0 c = 3 a = -6

a = - 6; b = 0; c = 3

-6x^2 + 3 = 0

F) a = -1 b = 0 c = 0

- x^2 = 0

G) a = 2 c = 5 b = 3

a= 2; b = 3; c = 5

2x^2 + 3x + 5 = 0
