Question 8

Vocabulary: Identify the expression as a sum of cubes, a difference of cubes, or a difference of squares.
NOTE: A Take Note: Concept Summary table in the Guided Practice activity indicates that 4x^{2}-15 is a difference of squares.
While it may be useful to factor the expression this way in specific situations, we will only consider expressions to be differences of squares if the constant is a perfect square.
For example, 9x^{2}-25 IS a difference of squares. 9x^{2}-5 is NOT.
