Factor the Trinomial : )
How would you do that?
1/16x^2 + 1/3x + 4/9
you want that in the form (ax^2 + b)^2
look at the first term, it is a perform square, so more than likely you will have
(1/4x + ?)^2
look at the last term, it is also a perfect square, so perhaps we have
(1/4x + 2/3)^2
expand it to see if the middle term is 1/3x .If so, we got it !
