# Precalculus 11 week 6

This week what stood out to me was finding out how to identify perfect square trinomials. below is an example of a perfect square trinomial.

$x^2+8x+16$

To make sure it is a perfect square trinomial you have to divide the middle number by 2 then square it, the number you get should be the last number if it is not that means it is not a perfect square trinomial.
