Lesson 5.2 will also cover Factors and Zeros with regards to solving a quadratic. The difference between these lessons is the following.

3.4 Factored Form of a Quadratic

Factors help find x-intercepts (we won’t practice how to factor in this lesson)
Briefly mention x-intercept is called a “zero”, or root.
Finding the axis of symmetry (half way between -intercepts).
Finding the vertex.
Sketching the graph.

5.2 Factors and Zeros

Factoring quadratics (both a=1 and a is not 1)
Focus is on solving equations.
Connection between factors – zeros – roots – x-intercepts. (review)
Multiplicity (will help with higher order polynomials)
Fundamental Theorem of Algebra (official definition)
