We started by looking at how to factor trinomials. One option is to write two sets of parentheses. From there I look first at the first term, then at the third term. And I use the middle term to guide my choices.
There is another method that uses similar ideas but that is laid out in four sections of a large X.
Talked about when the quadratic formula is useful and used it a few times.
Got into algebraic perfect squares.
Did a bit with inequalities.
Saw some complex numbers.
Used the Pythagorean Theorem once.
Looked at a parabola, intercepts, and symmetry.
