\[(2y + 4)(y + 1) = 36\]
\[2y^{2} + 4y + 2y + 4 - 36 = 0\]
\[2y^{2} + 6y - 32 = 0\ \ \ \ \ |\ :2\]
\[y^{2} + 3y - 16 = 0\]
\[D = 9 + 64 = 73\]
\[y_{1,2} = \frac{- 3 \pm \sqrt{73}}{2};\]
\[x_{1,2} = 2 \cdot \frac{- 3 \pm \sqrt{73}}{2} + 6 =\]
\[= - 3 \pm \sqrt{73} + 6 = 3 \pm \sqrt{73}.\]
\[Ответ:\left( 3 \pm \sqrt{73};\frac{- 3 \pm \sqrt{73}}{2} \right).\]
