Answer 1

Ответ:

1

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

1)

$2x - 3 = 0\\ 2x = 3 \\ x = 3 \div 2 \\ x = 1.5$

2)

$x - 2 = 0 \\ x = 2$

ответ:

$x1 = 1.5 \\ x2 = 2$

2

$x {}^{2} + 6x + 9 = 0 \\ (x + 3) {}^{2} = 0 \\ x + 3 = 0 \\ x = - 3$
