Question

me ajuda pro favor

14x2 - 4x = 0

4x2 + 4x + 1 = 0

x2 - 5x + 6 = 0

x2 + 100 = 0

x2 + 20x + 100 = 0

Answer 1

Resposta:

$14 \times 2 - 4x = 0 \\ x = 7$

$4 \times 2 + 4x + 1 = 0 \\ x = - 2$

$x2 - 5x + 6 = 0 \\ x = 2$

$x2 + 100 = 0 \\ x = - 50$

$x2 + 20x + 100 = 0 \\ x = - \frac{ 50}{11}$

Answer 2

Resposta:
