When solving a quadratic equation, it is necessary to write it in standard form first - that is, in the form 
. This equation is not in this form, so we must get it in this form as follows:
We factor the quadratic expression as
so that 
and 
.
By trial and error, we find that
, so the equation becomes
Set each linear binomial to 0 and solve separately:
The solution set is
