Tutoring Precalculus at MPC

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.
