Answer 2

Ответ:

1.

${m}^{2} - m = 0$

$m \times (m - 1) = 0$

$m = 0$

$m - 1 = 0$

$m = 0$

$m = 1$

$m_{1} = 0. m_{2} = 1$

2.

${a}^{2} + 10a = 0$

$a \times (a + 10) = 0$

$a = 0$

$a + 10 = 0$

$a = 0$

$a = - 10$

$a_{1} = - 10. a_{2} = 0$

3.

${7x}^{2} - 35x = 0$

$7x \times (x - 5) = 0$

$x \times (x - 5) = 0$

$x = 0$

$x - 5 = 0$

$x = 0$

$x = 5$

$x_{1} = 0. x_{2} = 5$

4.

${14n}^{2} + 18n = 0$

$2n \times (7n + 9) = 0$

$n \times (7n + 9) = 0$

$n = 0$

$7n + 9 = 0$

$n = 0$

$n = - \frac{9}{7}$

$n_{1} = - \frac{9}{7}. n_{2} = 0$
