A serious mistake is not realizing that the above expression is a special product and squaring each term incorrectly: Intermediate goods or producer goods or semi-finished products are goodssuch as partly finished goods, used as inputs in the production of other goods including final goods.

Square of difference formula This formula is very similar to the square of sum formula, with the difference of the minus sign in the second term.Special products of polynomials In the previous section we showed you how to multiply binominals.

There are a couple of special instances where there are easier ways to find the product of two binominals than multiplying each term in the first binomial with all terms in the second binomial. Special Binomial Products. So when we multiply binomials we get Binomial Products!

And we will look at three special cases of multiplying binomials so they are Special Binomial Products. 1.

Multiplying a Binomial by Itself. What happens when we square a binomial (in other words, multiply it by itself).? Special products of binomials: two variables.
