You can put this solution on YOUR website! I can show you the way I do it
Subtract from both sides
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
whew! This is a difficult one, but the
method is always the same
