Start with the given equation

Factor the left side (note: if you need help with factoring, check out this solver)

Now set each factor equal to zero:

or

or Now solve for x in each case

Since these two answers are the same, our only solution is

Notice if we graph we get

and we can see that the graph has a root at , so this verifies our answer.
