2. $x=\frac{1 \pm \sqrt{17}}{4}$

+ (3 points) - solution is correct

+- (2 points) - the main idea of transformations in the solution is correct (up to reducing the equation to a quadratic), but there are arithmetic errors further on

-+ (1 point) - only partial transformations are carried out in the solution.
