Solving 3rd and 4th Degree Polynomial Equations & Graphing Related Polynomial Functions

This 81 minute advanced algebra math video lesson was made available today at MATH MADE SIMPLE . It teaches viewers how to solve 3rd and 4th degree polynomial equations using:
- common factor
- difference of squares
- trinomials
- the quadratic formula
- the factor theorem
After viewing 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) the sign of the leading coefficient and the y intercept
One of the example questions:
Solve x^3 – 4x^2 + 2x + 7 = 0 and sketch the graph of the function
This lessons contains explanations of the concepts and 16 example questions with step by step solutions plus 6 interactive review questions with solutions.
