Terminology and Simplifying
2

• Basic terms allow us to identify particular parts
  of an expression
• Algebraic Expression made up many parts,
  including operations, constants, variables,
  powers and roots
• Expressions do not include an sign
• An sign implies a function, or equation

3
Basic Terms

• Constants fixed numbers (1, -4, 5i)
• Variables letters to represent unspecified OR
  changing numbers (4x, xy2)
• Evaluate replace variable with specified numbers
• Terms parts joined by or

4
Basic Terms, 2

• Factors parts joined by X or
• Coefficient constant factor of a term
• Variable Factor non-constant factor of a term

5
Identifying Pieces and Parts

• Example. Identify the following from 4x2
  2xy(z 5) 10
• A) Constants
• B) Coefficients
• C) Terms
• D) Factors
• E) Evaluate for x 2, y -1, z 0

Further Simplifying Radicals

• Following rules can allow us to further simplify
  radicals or confusing exponents
