Algebra II • Series of parameter driven, algebra exercises involving factoring polynomial expressions, quadratic equation, and using radical expressions involving square and cube roots. Gerald Chrisman Gateway Technical College
Algebra 101 • Students more fully understand factoring and the quadratic equation by simplifying equations with radical expressions. The equations contain square roots, cube roots, and squares and cubes of equations are used. The use of a mechanical device, calculator, may be required to check the answers. Students solving these exercises will enhance the understanding of factoring and solutions to equations. In addition the instructor can change the parameters, constants, to make each assignment different. The following three parts characterize three different skill levels.

PART 0 Factoring Gerald Chrisman Gateway Technical College
PART I • Instructing students about factoring trinomials as well as squares and cubes of equations is enhanced with exercises that are more challenging. • For instance in addition to the usual trinomial factoring problems include expressions such as; which reduces to the quadratic Thus, the student’s algebraic skills are easily evaluated.

Sample • Next introduce equations such as; . • Solving for x is a routine matter and the instructor can make many variations for practice. • The general solution, using parameters a,b,c follows. Gerald Chrisman Gateway Technical College

PART IIINext as students become more able to handle square roots introduce the cube root equations such as; Gerald Chrisman Gateway Technical College
This equation, when taken to the third power, has an interesting exercise property; it factors like this. Notice the original equation returns in the solution and a quadratic equation results. Gerald Chrisman Gateway Technical College

CONCLUSIONThe above examples provide the instructor with a variety of challenging algebra problems for students with various skill levels in algebra. In addition the parameters provide additional flexibility for instructors to repeat these exercises. These equations and others like them have assisted my classes more fully understand algebra as well as solutions that require mechanical checking, and several steps.
