[ ]² = 1

The value in the space is ...

[ ] = √1 = 1

The filled-in equation is ...

(3x -1)² = 9x² -6x +1

_____

The expansion of the square of a binomial is ...

(ax -b)² = a²x² -2abx +b²

Above, we used the constant term to find 'b', but we could also have used the linear term:

-6x = -2(3)bx . . . . . a=3 in this problem

1 = b . . . . . . . divide by -6x
