Let's say that we want to solve the equation x squared plus 8 x plus 15 equals
0:00:04.104,0:00:08.232
3. Well, we have two options. Our first option is to solve this graphically by
0:00:08.232,0:00:12.487
plotting the intersection of two different curves. And our second option is to
0:00:12.487,0:00:16.946
solve this purely algebraically. Let's start out with the first option. So, what
0:00:16.946,0:00:21.490
two lines should be graph in order to solve this equation graphically? What two
0:00:21.490,0:00:24.105
lines do we want to intersect?
