Answer 2

$1) {x}^{2} - \frac{11x + 2}{6} = 0 \\ 6 {x}^{2} - (11x + 2) = 0 \\ 6 {x}^{2} - 11x - 2 = 0 \\ 6 {x}^{2} + x - 12x - 2 = 0 \\ (6x + 1)(x - 2) = 0 \\ \bf x1 = - \frac{1}{6} \\ \bf x2 = 2$

$2)(x + 2 {)}^{2} = 43 - 6x \\ {x}^{2} + 4x + 4 = 43 - 6x \\ {x}^{2} + 4x + 4 - 43 + 6x = 0 \\ {x}^{2} + 10x - 39 = 0 \\ {x}^{2} + 13x - 3x - 39 = 0 \\ (x + 13)(x - 3) = 0 \\ \bf x1 = - 13 \\ \bf x2 = 3$
