Question

5) Correlacione as equações : * a = 9, b = –5, c = 0. a = 3, b = 4, c = 1 a = 1, b = –1, c = –1 . a = 5, b = 0, c = –4. a = 1, b = -5, c = 6. 5x² – 4 = 0 x² – x – 1 = 0 x² – 5x + 6 = 0. 9x² – 5x = 0 3x² + 4x + 1 = 0 5x² – 4 = 0 x² – x – 1 = 0 x² – 5x + 6 = 0. 9x² – 5x = 0 3x² + 4x + 1 = 0

Answer 2

Oie, Td Bom?!

1.

$5x {}^{2} - 4 = 0$

• Coeficientes:

$a = 5 \: , \: b = 0 \: . \: c = - 4$

2.

$x {}^{2} - x - 1 = 0$

• Coeficientes:

$a = 1 \: , \: b = - 1 \: ,\: c = - 1$

3.

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

• Coeficientes:

$a = 1 \: ,\: b = - 5 \: , \: c = 6$

4.

$9x {}^{2} - 5x = 0$

• Coeficientes:

$a = 9 \: , \: b = - 5 \: , \: c = 0$

5.

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

• Coeficientes:

$a = 3 \: , \: b = 4 \: , \: c = 1$
