if we have : (x + a)^2 and (x +b)^2 what will be the general form of the square of a binomial B ?

To find the square of a binomial B, where B is of the form (x + a) or (x + b), we can use the formula for the square of a binomial:

B^2 = (x + a)^2 = x^2 + 2ax + a^2

or

B^2 = (x + b)^2 = x^2 + 2bx + b^2

These two formulas represent the general form of the square of a binomial.
