Answer 2

$\frac{ {2x}^{2} - 3x - 14}{ x + 2} = 0 \\ {2x}^{2} - 3x - 14 = 0 \\ {x}^{2} - 3x - 28 = 0 \\ x1 + x2 = 3 \\ x1 \times x2 = - 28 \\ x1 = \frac{7}{2} \\ x2 = \frac{ - 4}{2} = - 2 \\ {2x}^{2} - 3x - 14 = 2(x - \frac{7}{2} )(x + 2) = (2x - 7)(x + 2) \\ \frac{(2x - 7)(x + 2)}{x + 2} = 0 \\ 2x - 7 = 0 \\ 2x = 7 \\ x = 7 \div 2 \\ x = 3.5$
