This course provides a study of problems involving algebraic representations of quadratic, rational, and radical equations. Topics include simplifying polynomial, rational, and radical expressions and solving quadratic, rational, and radical equations. Upon completion, students should be able to find algebraic solutions to contextual problems with quadratic and rational applications.


  1. Represent real-world applications as quadratic equations
  2. Apply exponent rules
  3. Solve application problems involving polynomial
  4. Apply the principles of factoring when solving problems
  5. Represent and solve contextual application problems involving operations on expressions and/or equations
  6. Explain the reasonableness of solutions found
  7. Solve radical equations
  8. Perform operations with radical expressions
