Quadratic Function
SPECIAL PRODUCTS
Special products and multiplying polynomials all relate to "Expanding and simplifying", There are two types of special products
Squaring Binomials
The first one is for squaring a binomial. You could use FOIL method as discussed earlier or you could, add the square of first term with twice the product of the two terms and square of the last term. If you do the opposite, you would be factoring, separating "2ab" and facotring anything outside. finally to group your expressions if they are both the same, they would become (a-b)(a-b) into (a-b)^2. (Binomial means two terms as "Bi" meaning "two".
When dealing with expressions like these again you could use FOIL method or, you just add the square of first term with the square of second term. To factor would be doing the opposite and that is by using the foil method and factoring out anything common. Finally when finshed grouping the terms, if your expressions has a "+" and "-", your expression is a first differences and "(a+b)(a-b)" is your final answer
