    How did you work out number 1? Just to be sure... For number two you should use the following algorithm: You have to reform the equation to an equation in like: \[ax^2+bx+c=0\] With a, b and c real numbers. Then you should determine your determinator \[D = b^2-4ac\] And the solutions are: \[x_{1} = \frac{ -b+\sqrt{D} }{ 2a }\] \[x_{2} = \frac{ -b-\sqrt{D} }{ 2a }\]
