Algebra: Solving 3rd & 4th Degree Poly Eqns 265

This lesson is part of the following series:

Algebra II (8 lessons, $30.69)

This 81 minute advanced algebra 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.

Lessons that will help you with the fundamentals of this lesson include:
- 130 Long Division of a Polynomial by a Binomial (http://www.mindbites.com/lesson/5064)
- 170 Factoring Polynomials (http://www.mindbites.com/lesson/5071)
- 205 Solving Systems of Linear Equations (http://www.mindbites.com/lesson/5083)
- 260 Polynomial Functions (Synthetic Division, Evaluating, The Remainder & Factor Theorems, Integral and Rational Zeros) (http://www.mindbites.com/lesson/5059)
