    You can either make a table or factor it to get started.

    You can get a rough idea of the graph from 2 things: 1) The coefficient of x² If it is positive, the graph will be concave up. (shaped like a 'U'). 2) Solve for x. The roots of the equation are -1 and -5 These are the two points where the parabola crosses the x axis. With this small amount of information, we can make a rough graph of the equation.
