Розв 'яжіть рівняння:

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

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

$x = 0$

$x - 5 = 0$

$x = 0$

$x = 5$

$x _{1} = 0,x_2 = 5$

______________________________

$x {}^{2} + 2x = 0$

$x \times (x + 2) = 0$

$x = 0$

$x + 2 = 0$

$x = 0$

$x = - 2$

$x_1 = - 2,x_2 = 0$

______________________________

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

$2x \times (2 - x) = 0$

$x = 0$

$2 - x = 0$

$x = 0$

$x = 2$

$x _{1} = 0,x_2 = 2$

______________________________

$5x {}^{2} + 15x = 0$

$5x \times (x + 3) = 0$

$x \times (x + 3) = 0$

$x = 0$

$x + 3 = 0$

$x = 0$

$x = - 3$

$x _{1} = - 3,x _{2} = 0$
