DMA 080 Radical Express/Equations (1 Credit Hour)


Class Hours: .75
Lab Hours: .50
Clinical/Work Experience Hours: 0
Prerequisites: DMA 010 , DMA 020 , DMA 030 , DMA 040 , DMA 050 , DMA 060  and DMA 070  or MAT 070  or appropriate placement test scores.
Corequisites: None
This course provides a conceptual study of the manipulation of radicals and the application of radical equations to real-world problems. Topics include simplifying and performing operations with radical expressions and rational exponents, solving equations, and determining the reasonableness of an answer. Upon completion, students should be able to find algebraic solutions to contextual problems with radical applications.

Competencies:

  • Solve contextual application problems involving operations on radical expressions and/or equations
  • Represent real world situations as radical equations and graphically using a graphing calculator
  • Explain the reasonableness of solutions found
  • Correctly perform operations with radical expressions
  • Use a graphing calculator to analyze radical functions

Student Learning Outcomes:

8.1 Demonstrate the use of a problem solving strategy to include multiple representations of the situation, organization of the information, and algebraic representation of radical equations
8.2 Correctly use rational exponents to rewrite radical expressions
8.3 Simplify radical expressions
8.4 Add and subtract radical expressions
8.5 Multiply radical expressions
8.6 Divide radical expressions
8.7 Solve radical equations
8.8 Solve quadratic equations using the quadratic formula
8.9 Graph radical functions using the graphing calculator to identify and interpret the graph in terms of the problem
