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.
And somewhere in Chicago, the servers at Kuta Software silently continue generating new versions of that same worksheet — changing the numbers, keeping the structure, preserving the rite of passage for the next generation. If you'd like, I can even reconstruct the actual 60-problem worksheet from memory/common Kuta patterns, or create an answer key. Just let me know. Kuta Software Algebra 2 Big Old Factoring Worksheet

A collective groan rises from 28 students. Years later, in college calculus, Alex sees: "Factor x⁴ - 16 to simplify this limit." Without hesitation, Alex writes (x²+4)(x+2)(x-2) . The person next to them asks, "How did you do that so fast?" Factor out (x²-1) : (x²-1)(x³ - 8)
Alex smiles. "Kuta Software. Big Old Factoring Worksheet. Sophomore year."
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.
