What does the generator do?
The generator picks one of the binomial formulas at random and small coefficients a, b. It builds the expanded polynomial and four options — only one is correct.
How to solve
Count the terms first. Three terms all positive → first formula. Three terms with a minus in the middle → second formula. Two terms with a minus between → third formula. Then read off a and b.
