Answer 2

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