1 simplify polynomial expressions by adding, subtracting, and multiplying

Sample problem: Write and simplify an expression for the volume of a cube with edge length 2x + 1.

2)verify, thorough the investigation with and without technology, that ab = a x b, a 0, b 0, and use this relationship to simplify radicals (e.g., 24) and radical expressions obtained by adding, subtracting, and multiplying [e.g., (2 + 6)(3 - 12)

4 determine if two given algebraic expressions are equivalent (i.e., by simplifying; by substituting values)

Sample problem: Determine if the expressions2x^2-4x-6 and 8x - 2x(4x - 1) - 6 are equivalent.
