Problem
The roots of the equation can be obtained graphically by finding the abscissas of the points of intersection of each of the following pairs of equations except the pair:
[Note: Abscissas means x-coordinate.]
Solution
If you find the intersections of the curves listed in the answers ,
,
, and
, you will find that their abscissas are
and
. Also you can note that the curves in
don't actually intersect. Therefore the answer is
.
