When , the first step is to rearrange the equation so that the term is isolated.
The left-hand side of the equation can now be expressed as the We'll draw its graph.
The solutions to the equation are the coordinates of the points on the graph that have coordinate
The solutions of the equation are
We can verify them by substituting in the given equation. We'll start with
makes a true statement, it is a solution to the equation. Next, we'll verify
in the same way.
makes a true statement, it is also a solution. Therefore, both
are solutions to the given equation.
