Use steps similar to what you've used for other graphs; namely, pick some x-values, plug them into the equation, solve for the corresponding y-values, and draw the dots. Continue until you have a good idea of what the graph should look like. Then draw in the line(s).

It might be simplest to solve this, once and for all, for "y="
. Then plug x-values in, etc, just as you always have for graphing linear equations

A potentially-useful extra step here might be to take the common factor out front
and then factor the remaining quadratic
. From this, you can find the x-intercepts easily. Then proceed (with plotting points, etc) as usual.
