 Solved by pluggable solver: SOLVE quadratic equation with variable Quadratic equation (in our case ) has the following solutons: For these solutions to exist, the discriminant should not be a negative number. First, we need to compute the discriminant : . Discriminant d=89 is greater than zero. That means that there are two solutions: . Quadratic expression can be factored: Again, the answer is: 3.2169905660283, -6.2169905660283. Here's your graph:
