Expand the expression using the second binomial formula.
(1x − 2)² =
x² − x +
What does the generator do?
The generator picks random whole numbers a, b between 1 and 7 and shows (ax − b)². The signs are fixed in the form — you only fill in the coefficients.
How to solve
Same as the first formula: square the first number, twice the product, square the second number. The only difference is the minus before the middle term.
