Question

x(5x-3)+x2=6x me ajudem por favor ​

Answer 1

Resposta:

$x = 0 \\ \\ x = \frac{7}{5}$

Explicação passo-a-passo:

$x \times (5x - 3) + x \times 2 = 6x \\ x \times (5x - 3) + 2x = 6x \\ x \times (5x - 3) +2x - 6x = 0 \\ x \times (5x - 3) - 4x = 0 \\ (5x - 3 - 4)x = 0 \\ (5x - 7) x = 0 \\ x = 0 \\ 5x - 7 = 0 \\ 5x = 0 + 7 \\ 5x = 7 \\ x = \frac{7}{5}$
