Identifying Factoring Patterns
Using all four factoring patterns from the last page, sort the following expressions by which factoring pattern could be used to factor each one. Use the headings below and list the appropriate expressions underneath. If they don’t fit in any category, then put them in the category labeled “None”.
Difference of Two Squares Perfect Square Trinomial
Difference of Cubes Sum of Cubes None
\(x^2+10x+25\) \(x^3+125\) \(2x^3+128y^3\) \((4x)^2-48x + 6^2\)
\(8x^3-27\) \(a^3-125b^3\) \(m^3 +8\)
\(121-y^2\) \((x-2)^2-49\) \(r^2-8r+16\)
