Algebra 2 (12 Lessons) (12 lessons, $32.67)
Advanced Algebra (5 Lessons) (5 lessons, $19.80)
Algebra Relations and Functions (5 Lessons) (5 lessons, $19.80)

This 81 minute algebra 2 lesson will show you how to solve 3rd and 4th degree polynomial equations using:
- common factor
- difference of squares
- trinomials
- the quadratic formula
- the factor theorem

After this lesson you will understand:
- the difference between a polynomial equation and a polynomial function
- how to identify real & non-real zeros
- how to sketch the graphs of 3rd & 4th degree polynomial functions using the zeros (x intercepts) and the sign of the leading coefficient and the y intercept.

Sample Question: Solve x^3 – 4x^2 + 2x + 7 = 0 and sketch the graph of the function

This lesson contains explanations of the concepts and 16 example questions with step by step solutions plus 6 interactive review questions with solutions.
