Intermediate Algebra

Intermediate Algebra is designed to prepare the student for MTH 140 and MTH 143. Topics include: solving linear equations in one variable; equations of straight lines in the two-dimensional Cartesian plane; solving systems of linear equations in two or three variables; laws of exponents; factorization of polynomials; manipulating rational and radical expressions. Minimum grade of C required for successful completion. Prerequisite: MTH 120 with a minimum grade of C or a suitable test score, ACT Math score of 18 (minimum) or a SAT Math score of 430. The course counts as an elective for graduation but may not be used to meet specific program requirements.

Upon completion, students will be able to:

  • Solve linear equations and inequalities using addition and multiplication principles.
  • Solve applied problems by translating to equations and inequalities.
  • Describe functions using graphs, tables, and equations.
  • Graph linear functions using slope and intercepts.
  • Solve system of equations by the substitution method and the elimination method.
  • Multiply and simplify polynomials including using the FOIL method to multiply two binomials.
  • Factor trinomials using a variety of methods.
  • Add, subtract, multiply, and divide rational expressions.
  • Simplify radical expressions and rational exponents.
  • Solve quadratic equations by factoring and the quadratic formula.
