Vertex form of quadratic equation, Tutoring Precalculus

We started by looking at some problems with division of polynomials. Chose to use synthetic division, long division would be an option also.

To fully factor, for example, a fourth degree polynomial, if it comes out without a remainder then the combination of all factors is the fully factored form. Like you could factor 12 as 2*3*2.

Another problem seemed to call for the vertex form of a quadratic equation y = a(x-h)^2 + k where (h, k) is the vertex. Then you could convert that to standard form.

Talked a bit more about imaginary numbers.
