Divide both sides by


Take of the coefficient of the
term, then square it, then add it
to both sides
-----------------------------------




Believe it or not, both sides are now perfect squares!

Take the square root of both sides


And, using the negative square root of the right side,


--------------
So, the factoring would be:



Multiply both sides by

Divide both sides by
