Let's say that we want to solve the equation x squared plus 8 x plus 15 equals
3. Well, we have two options. Our first option is to solve this graphically by
plotting the intersection of two different curves. And our second option is to
solve this purely algebraically. Let's start out with the first option. So, what
two lines should be graph in order to solve this equation graphically? What two
lines do we want to intersect?
