1. &gt;&gt; Since we know what points of intersection, the y value for the two lines that
2. are crossing through there will be the same, we can set 0 equal to negative x
3. squared over 8 plus 4x minus 14. And that's the equation we need to solve. The
4. solutions to this equation, values of x, will give us then the x values of the
5. points where these two lines intersect.
