can be written as
and bringing the common factor to the front, gives the factors:
solving the equation for gives the solution meaning that the graph of the equation crosses the x-axis at the point (2,0)
solving the equation for gives , meaning that the graph of the equation crosses the y-axis at (0,-2)

We will use a factoring method called grouping. If we group the first and the third and the second and the fourth together, each grout has its own greatest common factor:
Now we see another CF between the two terms : . We can factor it out.
