Sign Inversion during Root Extraction
MISTAKE DETECTED
In Step 4, when setting each linear factor to 0: for \(2x - 1 = 0 \implies 2x = 1 \implies x = 1/2\) (not \(-1/2\)), and for \(x + 3 = 0 \implies x = -3\) (not \(+3\)). Both roots were inverted in sign.

Correct Step 4 formulation:
x = 1/2 or x = -3
