By Problem #50, Alex’s hand cramps. By #55, they begin questioning their life choices. By #60 — x⁴ + 4 — a special "sum of squares" that factors using the "plus/minus 2x" trick: (x² + 2x + 2)(x² - 2x + 2) — Alex almost cries with relief. Ms. Garcia, the Algebra 2 teacher, has assigned this worksheet for eight years. She knows its power. "The 'Big Old Factoring Worksheet' isn't about memorizing answers," she tells her colleagues in the teachers' lounge. "It's about pattern recognition under pressure. By the time they finish, they've seen every possible factoring case."
Problem #25: 16x⁴ - 81 . Difference of squares? Yes: (4x² - 9)(4x² + 9) . Then the first factor is difference of squares again: (2x-3)(2x+3)(4x²+9) . Check! Kuta Software Algebra 2 Big Old Factoring Worksheet
She also knows that students will search for answer keys online. Kuta Software sells answer sheets to teachers, but students often find scanned copies on Quizlet or Course Hero. She doesn't mind — "Even if they peek, they still have to understand the steps." Alex finishes at 11:47 PM. The worksheet is filled with arrows, scratched-out terms, and tiny numbers from the quadratic formula. They check the back: the last problem is x⁸ - y⁸ — which factors down to (x⁴+y⁴)(x²+y²)(x+y)(x-y) . Alex writes it, closes the notebook, and stares at the ceiling. By Problem #50, Alex’s hand cramps
By problem #18, doubt creeps in: 3x³ + 24 . GCF of 3 gives 3(x³ + 8) . Wait — sum of cubes! 3(x+2)(x² - 2x + 4) . Phew. "The 'Big Old Factoring Worksheet' isn't about memorizing
But then comes : x⁵ - x³ - 8x² + 8 . Grouping? Try: x³(x² - 1) - 8(x² - 1) . Factor out (x²-1) : (x²-1)(x³ - 8) . Then (x-1)(x+1)(x-2)(x²+2x+4) . Alex writes the answer, erases it twice, then writes it again, heart pounding.
Alex smiles. "Kuta Software. Big Old Factoring Worksheet. Sophomore year."
